Anesth is a numbing agent that dentists use for pain relief in the mouth.


Nobody looks forward to going to the dentist. You tend to associate trips to the dental office with anxiety and pain. Whether it's for a routine check-up or a tooth saving procedure, the dread of being seen is almost universal. Dentists do everything they can to prevent their patients from feeling pain. Gas, pills, and topical anesthesia are all possibilities. But cavities, dentures, braces, blisters, sores and the normal process of teething all cause issues that dental professionals can choose to treat with topical medications. We all want to look our best, and dental appliances treat many cosmetic conditions, but sometimes the trade off is the occasional case of major discomfort. Painful swelling from the friction between your partials or braces and your gums may begin as a non distinct irritating throb, and end up causing major mouth pain. Your dentist may sometimes prescribe lidocaine following a procedure to provide relief from sore throat pain. Your dentists may recommend other pain relief options for throat pain, such as dyclonine, menthol/benzocaine mixed, and benzocaine.

Most oral health problems are not serious and clear up within a few days. Other issues like canker sores that just won't heal may be signs of a serious health condition like cancer of the mouth. After treatment of a minimum of one week contact your doctor or dentist if the issue persists. Be prepared to talk with the doctor about your health history and all the possibilities that may have caused the sores to occur. What were you doing before you felt the first sign? What were you eating? Did you kiss somebody? Were you putting on make-up? Did you have a cold?

The first sign of a canker sore is irritation, itch, then a burning sensation in the area. Simple things like eating your favorite foods or having your regular drink will become painful and you'll notice a tiny, irritated bump in the inflamed area. Only a doctor can diagnose life threatening diseases such as cancer. If you have a concern that your condition may be more serious than a canker sore immediately contact your doctor.

Becoming feverish while on this medication is no cause for alarm. There are common side effects to some of the conditions that require Anesth. Multiple canker sores can cause fever, so check in with your doctor or dentist to determine if your fever is caused by the condition or the medication. If your mouth or throat becomes infected seek medical attention for additional medication and to be reevaluated by your doctor. Once your canker sore changes color from red to white or gray you know it's healing.

If the fever is not a occurring due to the medication, your doctor will reevaluate your case and determine a proper plan of action to treat you.

Check in with the dentist at your follow-up appointment and report any lingering side effects.

You or your dentist can apply topical anesth to your mouth. The agent is put onto a cotton swab and applied to the area where the pain is occurring. It is also used as a numbing agent for the area in the mouth that is being prepped for a procedure. Only your doctor can determine the strength of the dosage of Anesth. The dose depends on age, weight, the severity of your condition, and length of time you've had the pain. After treatment is over your dentist may advise you to try an over the counter option for pain relief.

You do not need a prescription for Anesth. To receive the full benefit of this drug follow the instructions given by your doctor about application. Apply Anesth as needed to the area in the mouth that is in pain. Your doctor may increase or decrease the strength of the dosage based on the severity of your side effects. To receive the full benefits of this medication, only apply the amount suggested by the dentist, don't over apply because you don't know what your body's reaction will be.

Local anesthetic of any type is not recommended to be mixed with this medicine. They tend to amplify certain side effects of the medicine. You will become more drowsy, more tired, more confused and your vision may be impaired. Do not use any nonprescription ointments, gels, liquids and aerosol spray pain relievers in your mouth while using this medication. The active ingredients in one may cancel out the active ingredients in the other. Your doctor will inform you of any other specific instructions that pertain to your condition.

Take your first dose of Anesth and track your side effects before driving or operating heavy machinery. You don't know how the body will react and how intense the side effects may be. They may not occur at all or be extremely mild. Make a list of what side effects you experienced while on this medication. Once you go for a follow-up share any negative side effects, or side effects that were debilitating with your dentist. Every patient's body reacts differently to all medications, so check and see how your body reacts to this medication first. Side effects may be strong in the beginning and the severity may subside during the duration of your treatment


Discuss your medical history with your doctor or dentist at the initial consultation. It's never a good idea to mix medications without your doctor's consent. Any mixing may cause an adverse reaction that could be life threatening or debilitating. Make a record and create a list of all current and past medications you are taking. The dentist or doctor will determine whether or not you can still continue your meds while using Anesth. Create a list of all current and past medical conditions you experience. Some medical conditions may prevent you from being a candidate for this treatment. If you cannot use Anesth for pain, your doctor or dentist will find an alternate method of pain relief to treat your condition that is safe. If an adverse reaction occurs while using this medicine, your doctor may decrease your dose or the doctor may decide you are not a candidate for this treatment.

Notify your doctor if you are currently taking Ibutilide, Acecainide, Sotalol, Amiodarone, or Dofetilide. If you are using these medications your doctor may alter your prescription or dosage and decrease it due to possible reactions. Some of these medicications may have no reactions at all and you might be able to take them while using Anesth with no problems. You may not be a candidate for Anesth if you are taking any of those medications.

Do not smoke, drink alcohol, or use drugs while on this medication, it amplifies the side effects and increases the chance of dizziness, nausea, numbness, dizzy spells, weakness, and fatigue. Drugs and alcohol may cause an adverse reaction and increases the chance for serious life threatening side effects.

Aside from accidentally injuring yourself from biting your mouth and cheeks while using Anesth, some food may have an adverse reaction when mixed with Anesth. Your doctor will inform you of what you can and cannot eat or drink before you apply this medication. Adhere to your doctor's orders to successfully treat your pain.


Anesth is only to be applied to the area determined by your dentist. Do not apply Anesth to any other part of your body unless directed by a doctor. Do not rub medication intended for the mouth on to your knees, achy joints, face or any other areas. The ointment may burn the skin if applied in an area it's not meant to be used for.

Do not swallow this medication, it is not meant to be ingested directly into the internal body system. If ingested Anesth may cause nausea, vomiting and other reactions. Call your doctor and make an appointment to be seen if you do accidentily ingest Anesth.

  • Anesth should not be used if you have an infection in your mouth. The infection would have to be treated first before your dentist could give you this medication. It will not treat the infection. The presence of sores or infection are warning signs of other possibly life threatening problems. The dentist will check to make sure your mouth is healthy enough for them to recommend the medication. Your dental professional may refer you to seek care for the infection before prescribing Anesth.
  • Notify your primary physician if the pain persists or gets worse. If the pain causes blurry visions and migraines immediately call your doctor.
  • Sore throat that lasts longer than 48 hours should be reported to your primary physician.
  • Pain that lasts more than one week from mouth sores is a sign of another condition that can't be treated by Anesth. You may require a dental or medical procedure to alleviate the pain. Your dentist may refer you to your primary care physician for treatment.
  • Immediately contact your dentist if you throw up, run a fever, break out in an unusual rash, get migraines, the mouth/lips/throat swells up, or you feel sick to your stomache. These could be symptoms of a more serious condition.
  • You cannot chew anything while your mouth or throat is numb. No gum or food. The numbness may cause you to bite your cheek or tongue by accident. Wait until you get feeling in the mouth again before attempting to eat food.
  • Serious injury can occur. Attempting to swallow while the throat is numb is a choking hazard. Wait 60 minutes before you try to chew, eat, or swallow anything.
  • If your dentist advised application of Anesth to the back of the throat, choking may occur if you attempt to chew, eat, or swallow. Apply the medication as instructed to also prevent choking. Wait a minimum of 60 minutes from application to try to swallow.
  • Anesth is only prescribed or used for temporary relief of pain in the mouth. Any long term toothache, canker sores, or sore throat should be immediately checked by your doctor. Those are signs of more serious medical issues.
  • Talk with your doctor about how long to expect some discomfort from your dental appliances or dentures. You may have to make an appointment with your dentist for an adjustment in your dental appliance or braces if unusual pain occurs. It may take a few adjustments before the fit is right. Slight soreness or awkwardness is expected when you first receive the appliance, but should eventually subside.
  • Your dentist may advise you to apply Anesth before putting in your denture or dental appliance to avoid any pain or discomfort. Numbing the gum area before insertion may ease the discomfort and completely prevent any pain.
  • Wait 3 days before taking any type of lab tests that incorporates bentiromide while using lidocaine or benzocaine. You run the risk of fake positive results.

Additional warnings

At your initial consultation, create a list of any allergic reactions to this or other medications. Share any family medical history concerning cancer, diabetes, and blood conditions. Inform your doctor if you are currently being treated for any viral infections, you may not be a candidate for Anesth until the infection clears up.

Tell your doctor about all allergies including those to animals, food, food dyes, and preservatives. Some allergy medications may increase the chance for serious side effects. Certain allergy medications can't be mixed with Anesth because they cause drowsiness or have other side effects. Allergy medication may amplify the side effects of Anesth and may not be able to be mixed.

Do not operate a car or heavy machinery if you experience drowsiness, dizziness, confusion, blurred vision or headache while on this medication.

Your pediatrician will determine if your child is a candidate for Anesth. Side effects are stronger in children, and this medication has a greater chance of causing serious side effects in children. Some side effects may not be severe, but they may be stronger than normal. Follow the doctor's exact instructions when applying dental anesthesia on children. Teething babies aged 16 weeks or older are candidates for use of medication with benzocaine. Do not allow your child to drink or chew while the medication is active, the child is at risk of serious injury from biting their tongue or cheek. Do not use more than one medication that contains benzocaine at a time on children aged 4 months to 6 years - the side effects could be severe and possibly life threatening. The doctor will determine whether or not your child is a candidate for prescription or non prescription Anesth.

The side effects of lidocaine and other local anesthetics are stronger for the elderly. They are at higher risk for serious and adverse reactions to any medication. Follow the instructions given by the doctor, and whatever additional instructions come with the medication. Do not overuse Anesth during your treatment, most medications that are over the counter that contain local anesthetics are harmless to most patients. Notify your doctor if you experience severe side effects, your doctor may determine you are not a candidate for this medication and take you off Anesth. Elderly people that currently take other medications that contain lidocaine may not be a candidate for Anesth.

You can use Anesth if you are pregnant or plan on becoming pregnant. Lidocaine and other dental anesthetics are not proven to cause birth defects. If you are currently breastfeeding or plan to breastfeed, Anesth is safe for use as it has not been proven to effect babies that are still nursing.

To prevent further pain follow these steps while treating your condition:

  1. Use a soft toothbrush and gentle toothpaste with no lauryl sulphate. Toothpaste that contains lauryl sulphate may irritate and burn the mouth.
  2. Do not eat spicy food that contains pepper, hot sauces etc. Acidic foods are not recommended, and avoid extra crunch or hard foods while on this medication. They will burn your mouth and increase the pain.
  3. Do not drink coffee, tea, or other hot drinks while taking Anesth.
  4. Rinse out your mouth with anesthetic mouthwash everytime you eat and brush to kill bacteria and fight infection.

People sometimes confuse canker sores with cancer. You have to become aware of the signs and symptoms especially if oral cancers run in your family or you are a smoker. If you think you are suffering from a life threatening disease like oral cancer contact your doctor immediately. Cancer of the mouth occurs in the mouth area, lips, tongue and throat. If you have multiple breakouts of hard to treat canker sores or infections in the mouth look for the following symptoms of oral cancer:

  • Loose teeth
  • Canker sores that last more than 7 days
  • Swollen nymph nodes
  • Tongue patches that are red or white
  • Fast weight loss for no reason
  • Throat infection resulting from unexplained hoarseness
  • Persistent mouth pain
  • Lock jaw or jaw pain

If you experience any of the above symptoms immediately make an appointment to see your health care professional. Don't self diagnose, your doctor will determine if you are at risk of having oral cancer or any other life threatening disease.

Your dentist will screen you for oral cancer at your yearly check-up before prescribing Anesth. Those that have a history of mouth sores or conditions that effect the mouth may be referred to a specialist for further testing.

The best way to prevent painful conditions of the mouth is by maintaining a strict oral health regimen. Visit your dentist at least twice a year for your regular check ups, brush your teeth three times a day with an electric toothbrush, use an oral rinse like Listerine to fight bacteria, infection, gum disease and gingivitis, and eat a low sugar diet to prevent tooth decay. Stay away from sugary sodas, and too many sweets like cake, cookies, processed fruit fillings etc. Don't eat a lot of candy. If you do choose to eat candy don't fall asleep with it in your mouth. Hard candy in particular should be avoided because it dissolves and hardens in the nooks and crannies of your mouth, causing decay.

Make lifestyle changes will be recommended by your doctor and dentist after treatment is complete. Eat healthily to keep a strong immune system for fast healing, drink lots of water to stay hydrated and prevent dry mouth. Do not use other people's lip balm, lipstick or anything that someone has allowed to touch their mouth.

Avoid any mouth to mouth contact with strangers. Don't kiss people you don't know.

Don't allow people to kiss your babies and children on the mouth.

Don't share retainers, dentures, or mouth jewelry.

If you have constant dry mouth, bad breath, or a thick white coating on your tongue, consult your dentist immediately as these are signs of more serious conditions. Don't attempt to self diagnose or diagnose other people. Only a licensed dental professional or physician can determine what the cause of your condition is, and determine a course of treatment. Don't self medicate to attempt to address the pain. Take the medicine prescribed by your doctor to treat the pain. Don't take other people's pain medicine, or use other people's Anesth. Go to your own healthcare professional to receive medication. Anesth is given to patients on a case to case basis. Some patients may need prescription strength and some patients may not require a prescription. Your case may require a stronger or weaker dose.

Don't deviate from the doctor's orders. Too much Anesth may have an adverse affect on the body. If the numbness lasts longer than what the doctor initially told you, contact the dentist to find out if lingering numbness is normal.

Don't apply this medication to any exposed skin or exposed gums. Anesth has the tendency to cause an intense burning sensation if applied to exposed skin. Rub ice onto areas that the Anesth may have over medicated - these areas will take longer for the feeling to return but the ice will combat the irritating tingling that occurs.


Keep all medications out of the reach of children and those it is not prescribed to. Keep medicine in a safe place like a locked drawer or cabinet. Store Anesth tightly closed in the container that it comes in and out of direct heat, and sunlight. Store at room temperature.

If a child gets access to Anesth and applies it to any part of their body contact a doctor immediately. Consider taking the child to the emergency room if the skin is sensitive (it may show irritation or slight burns).


Dental professionals have numerous options to treat your pain, but topical Anesth is one of the safest pathways to a painless experience. Some people are too scared, nervous, and anxious to receive anesthetic with a needle and Anesth is easy and painless to apply. No bracing for the long needle, or getting that horrible feeling in your gut waiting for the needle to pierce your gums. It has been reported to cause the least side effects in patients than all other local anesthetic options. Applying it to the achy area is an easy task rather than walking around with a throbbing mouth. So whether it's a toothache, canker sore, pain in the throat, or you're having a procedure, Anesth is a safe way to numb and prevent the pain.
