hello
thanks for query
no friend your symptoms do not suggest a nerve damage...may be you are having some periodontal problem in lower front teeth... you should visit a dentist and get an x ray done for the affected area to make clear diagnosis.. scaling and root planing is advisable...a periapical infection is also possible...
you can go for warm saline rinses 3-4 times a day and also take vitamin b and vitamin c supplements once daily... maintain proper oral hygiene...
take plenty of fluids and avoid extreme cold drinks or food...
tightness and clenching of jaw can be due to extraction of third molar so you can take some pain killer in combination with a muscle relaxant bout only after consulting your dentist...
thank you

Hi there,
Thanks for asking your query,

What was the reason for extraction of wisdom tooth ? Wisdom tooth have to be extracted only if they are impacted.because impaction may cause pain and discomfort.

From your symptoms i suspect TMJ pain.A misdiagnosed temporomandibular pain can lead to the extraction of a wisdom tooth. The dentist should properly evaluate the possibility of tmj problems before proceeding to any therapy .Confusing a tmj tooth pain with a wisdom tooth pain is the most common case of misdiagnosing tmj problems.

Relief can be obtained for mild pain by taking prescription drugs like ant-inflammatory and muscle relaxants.but visit to an Oral and maxillofacial surgeons who are specially trained for treating temporomandibular joint will solve your problem.

meanwhile maintain a good oral hygiene,
hope this will help you,
regards,
Dr.naveen
