it most likely is your wisdom tooth I just went thru that it would be painful for a while then go away it was never consistent if it is a wisdom tooth u may not have enough room for it to come in an that is causing the pain. I didn't go in right away an the more it came in it eventually cracked 2 of my other molars causing a severe infection. go to the dentist they may just have to remove that wisdom tooth I unfortunately was born with 6 wisdom teeth very rare but happens. just go to the dentist it cud take up to 3 yrs. for your wisdom tooth to fully come in mine hadn't even broken the skin before it cracked my molars, hope this helps.
I think it may be your wisdom teeth.But for confirm this you have to contact to a good dentist.After doing X-ray he confirmed this.
It could be a cavity or the wisdom tooth or may be a you have been chewing something really hard. You should consult a doctor.
You're correct that it could be your wisdom tooth. Without seeing an x-ray it's impossible to say for sure, so your best bet would be to see a dentist and have an x-ray taken in the area that's bothering you. It doesn't seem like this problem is going to resolve itself on it's own.
Good Luck
When was your last dental visit?
It could be a cavity forming on one of your molars that's causing a pulpitis (inflammation in the pulp chamber of the tooth).
