Decay (a rotten tooth, caused by insufficient cleaning), or perhaps a part of the tooth has chipped off. Go to a dentist, who will probably give you a filling.
I recently had a trip to dentist for tooth extraction, and the oral surgeon accidentally broke the crown of my tooth while trying to pull it. Not only did the surgeon have to go into the gum, but he also had to dig around my jaw bone with a scraper and a drill for what seemed like the better part of an hour to get the remaining fragments of the roots out. It was highly uncomfortable, but tolerable. So to answer your question, yes. There is a chance the dentist might have to go into the gum, and possibly even the bone, to get a tooth out. Go to the dentist soon anyway. Dentist may be able to save the tooth with a cap.
A dentist can do a couple of things to a bad tooth. If the tooth is salvageable, the part that is bad will be carved or drilled out, then filled. If the entire tooth is bad, then the dentist will simply pry it out and offer options to replace it.
Dental fillings are quite simple. First, the dentist will ask you weather you want to have an injection to numb your mouth so you do not feel any pain. If you do decide to have an injection, the dentist may put some numbing gel on the place of injection or they may not, it really does not make any difference. The dentist will then leave you for a minute while the anesthetic takes affect. Next, the dentist will use a drill to drill out the decayed and weakened parts of the tooth. This may feel a bit funny but should not hurt. Then the dentist will wash and dry the now clean cavity. Finally, the dentist will place a special underlining, such as resin, to protect the nerves and blood vessels. Then the filling will be placed into the tooth. Depending on the type of filling, it will dry in a few seconds or the dentist may use a blue light to set it. Good luck on your filling. I speak on experience, I had a filling done a few hours ago.
because dentinoenamel junction locate between the two hard important part of the tooth and these two part of the tooth protect the tooth.
if its a big tooth then probably other wise not
no they can not because your tooth is to sensitive and you will wake up
Yes if during removal of a tooth or teeth part of the bone has to be removed, the Dentist can prescribe steroids to help the socket and bone to heal.
Have a dentist fill the cavity with or without a root canal, and while you're there, have him pull that tooth before the infection goes into the jawbone and you have to have part of your jaw removed. The dentist can also show you how to brush and floss your teeth to slow down further tooth damage.
Go to the dentist they will probably numb it and then pull it out or they will take your tooth out and sew it back up and then put it back in but that's normally only for permanent teeth (:
The hard painful lump near your growing wisdom tooth is probably part of the tooth. However, it could be an infection under the gums and should be checked by a dentist.
Most of the time they get sensitive because part of the tooth root is showing. Exposed root surface means that hot and cold feelings can reach the nerve of the tooth easier causing sensitivity from the nerve of the tooth. Brushing to hard, in the wrong direction or with whiting toothpaste can cause this sensitivity. This is not to be confused with pain when drinking or eating hot or cold things. Pain could indicate an infection in the nerve of a tooth. And needs to be treated with anti-biotics and root canal treatment or extraction.
