You often get into this mess of losing part or whole of the tooth, and this is actually a nasty situation in several ways. You may get severe pain there, or the sharp edge of the broken tooth may cut the cheek and other areas of the skin in the mouth white chewing or biting. Besides, if left untreated the broken part may accumulate dirt and food particles and can later form serious infections in the gum too. It looks bad too when a front tooth is broken, and often leaves your inner mount with cuts and abrasions when the sharp edge of the broken tooth rips of skin inside the mouth as you chew.

The first aid part

There are several ways to manage the broken tooth, and the first steps of first aid after the incident are as follows:
-  To control the acute pain after the tooth break, you may take a painkiller like acetaminophen. This will soothe the pain, and make it much easier and bearable.
-  You must try sticking some sugar-less chewing gum on the tooth to prevent cutting inside the mouth. In case a gum is not available, you may try putting some simple wax in there.
-  Try gulping the food and chew less, or go on a liquid diet to avoid touch of much food with the broken tooth unless it gets the first treatment.

Filing and Bonding- the initial treatment
On going to the dentist based on the tooth break condition, you will be suggested various remedies. A tooth filing or bonding is the general remedy. If a small portion of the tooth is broken, then the tooth can be simply filed in case it is one of the rear teeth. The tooth will be chipped and filed to smoothen the cut edge so that it never again pokes the skin around. 
If the break is not small, then bonding is a good option. The dentist fills the rest of the tooth space with a resin or porcelain material to make it look whole and natural again, and this solves the problem both physically and cosmetically.

Crowning the tooth
If the tooth is damaged more than a root canalling may be needed, and thereafter a cap or crown will be worn over the broken teeth so that it gets a natural look and the hardness to chew. You may lose sensations permanently on the tooth if the root nerve is blocked during the process. Else you will have a cosmetically working tooth for a few years until the crown wears off and needs a re-crowning.
