My molar 14 is crowned and root canaled but it feels a bituncomfortable. My molar 3 is crowned and feels good and normal. Is it normal or unusual?

It could be related to deficiencies with the root canal treatment, bite related, the fit of the crown, etc. If it uncomfortable and not improving, seek the advice of an endodontist for help. ...Read more

A month after root canal and crown my pre-molar still hurts. The dentist checked it twice and said the  canal looks perfect. Is this just sensitive?

CBCT: It might be a bite problem, a micro fracture in the tooth or root, an unfilled accessory canal or some other problem that cannot be seen either on clinical exam or with 2-dementional x-ray. You might want to have a consult with an endodontist who can take a cbct (cone beam ct 3d scan) which often shows previously undetectable problems. Or you can wait it out awhile longer. ...Read more

My tooth is sensitive to cold after 4-5 months after filling, why is that?

Many possibilities: If your tooth was not sensitive before the filling and has been sensitive since the filling, there could be a problem with the filling which should be rechecked by your dentist. If the cavity was deep the pulp or nerve may be irritated. This may lead to a root canal if the condition worsens. Either way after 4-5 months this should be rechecked by your dentist. ...Read more

My right side tooth became sensitive after a deep cleaning. Is this usually the case?

My right side tooth became sensitive after a deep cleaning. Is this usually the case?

Cleaning sensitive: Yes. Deep cleaning removes root tartar or calculus from the roots. Before it is remove gums are puffy, engorged with blood that is there to fight the germs on the calculus. Once this debris is removed the gums become healthy and shrink. Root surfaces are exposed. These initially are very porous and allow temperature changes to hurt the tooth. Apply a small amount of tooth paste before bed to roots. ...Read more

I had a left molar tooth extraction 3 days ago and now my tooth right next to it is very sensitive to touch with a toothbrush. Is this normal?

I had a left molar tooth extraction 3 days ago and now my tooth right next to it is very sensitive to touch with a toothbrush. Is this normal?

No, but common: While sensitivity is not normal, it is a common occurrence. It may be related to the adjacent tooth temporarily having no gum covering the root surface. As the extraction site heals, the sensitivity usually subsides. It may also be related to local inflammation. If it does not get better, have your dentist take a look to make sure no other treatment is necessary. ...Read more

Hi. On Tuesday I got a standard dental cleaning. Now today the gum behind my lower left wisdom tooth which is fully erupted and not impacted is swolle?

No worries: No worries...this is a common thing to happen around a back wisdom tooth area due to the type of tissue and how it will heal from a cleaning vs other areas. Not to say that the hygienist might have been a little to thorough in that area but I would clean/floss as normal, take some IBU for inflammation and do a warm salt rinse 2x per day until better (1-3days) ...Read more

Your own dentist can tell you whether or not it should be removed or left to erupt naturally. ...Read more
