Question: I had cavity in my lower left molar teeth. I filled in 1.5 year back. Now the filling is not there and there is hole. I need to do the filling. I was having little sensitivity . So doctor gave few medicine to take now. He said only when there is no sensitivity the filling can be done. Is it really necessary to wait until the sensitivity is not there ?

Thanks for writing in.

Based on the details provided, I think the sensitivity is due to exposed dentin in the open cavity of lower left molar teeth. I do not find it necessary that we should wait to restore the tooth until sensitivity stops unless you have supper added infection.

The exact treatment also depends on the extent of decay of the tooth. Have you got the x-ray of the tooth? If not, I would suggest getting X-rays to find out whether the decay is only in dentin or is it involving pulp.
- If only dentin is involved it can be restored as usual.
- If pulp is involved, treatment has to be planned depending on the severity of condition i.e., either pulpotomy/indirect pulp capping OR root canal treatment has to be done.

Discuss with your dentist further.

Hope this suffices. Please feel free to ask if you have any more queries.

Thanks for taking this message - I need a dentist's reply. I went in for a tooth bonding, but there was persistent pain. I was placed on anti-biotics for bacterial infection, but the next dentist I saw said the former didn't check my bite, which was the problem. That dentist shaved down the bond, and I left her office in very real pain. The sensitivity has since decreased, but not completely subsided. It does not wake me up at night, but I feel it just a few minutes after waking and then throghout the day. I can't handle this constant pain to my brain, albeit slight. I am not prepared to go for root canal - i would rather live every day with slight pain than that. It's been almost two weeks since the bond shaving, but I'm convinced the pain will not go away completely. If the nerve is agitated, I'm thinking that a re-bonding can't help b/c the nerve will be hit even further b/c it will involve slight further infringement on my tooth enamel, nor do I want to pu the tooth through any more stress in the short term. CAN YOU TELL ME WHAT IS LIKELY OCCURRING AND WHAT I CAN DO? My dentist says there should not be any exposed dentin, but I've been using sensitivity toothpaste anyway just in case. THANKS..

Hi, I'm 19 and I noticed today that I have what looks to be a small hole--maybe 1.5 mm across, plus maybe a tiny one that might forming between the next pair of teeth to the left--in the gums immediately to the left of the piece of skin stretching from my lower lip to the teeth in the lower front part of my jaw. A few months before this all I'd noticed was that my gums were receding a little to where I could see the dentin, especially on my lower canines, and I've been using a softer tooth brush since then. Can anyone tell me what this might be from and how I can fix it? Thanks.

I am a 23 year old female. I had healthy teeth, and got my front two teeth bonded to cover white spots at the bottom of my teeth. I had another dentist polish a scratch away but accidentally polished the bond off my right tooth and had another dentist in the same office re bond my right tooth. She did a sloppy job and i went to another dentist to attempt to smooth it out with a drill. My right tooth is depleted of enamel. I have light sensitivity. I wonder can still have porcelain veneers?
