Numb teeth are normal if you experience the numbness shortly following a dental procedure, due to the anesthetic used. However, your teeth being numb for a long time after dental procedures, or in any other situation, should be cause for concern. You should reach out to us if this occurs because numb teeth can indicate more serious medical conditions.
General tooth numbness can indicate underlying infection, decay, or other damage to the tooth. You may have nerve or blood flow damage because of these conditions. There are a variety of medical conditions that also cause numbness throughout your body, including in your teeth. For instance, some of these include vitamin deficiencies, low blood sugar, oral injury, allergic reaction, oral cancer, and burning mouth syndrome. There are more serious medical conditions, such as seizures and stroke, which affect the nervous system as a whole. Generally, with these more severe conditions, you are likely to notice additional symptoms other than your teeth being numb.
Numbness After Dental Procedures
The use of local anesthetic for certain dental procedures, such as extractions or cavity fillings, will cause your mouth to go numb. This effect can last several hours, up to five in some situations, and this is normal. Following these procedures, you should start to feel the numbness wear off gradually. However, although rare, nerve damage from anesthetic use and other procedures is possible. This condition is called paresthesia and usually occurs immediately following the procedure. This condition occurs in about 0.35% to 8.4% of procedures. It is also possible that you could experience a delayed onset of this condition as a result of these dental procedures. This is called delayed paresthesia. Paresthesia often goes away on its own, but it is possible that you would need further medical treatment. It is important to contact us if you notice any of these symptoms.
