1. You have a gum infection
Various bacteria can cause inflammation of the gums, which is quite painful, especially if purulent 'pockets' are created around the teeth. The dentist will clean out those pockets and prescribe an antibiotic to cure the infection.
2. You suffer from nocturnal bruxism
It is the name given to the unconscious grinding, grinding or clenching of the teeth which is often caused by stress. This phenomenon can cause tooth damage and pain, especially if it is daily. In that case, the dentist will recommend a special plastic cover that prevents the wear of the tooth surfaces.
3. You have a sinus infection
During flu season or allergy season, you can get a sinus infection. The root of a certain tooth can sometimes be located very close to the sinus, so pressure on the sinuses, i.e. we also feel the pain in them like a toothache.
Instead of a dentist in that case, a doctor will treat you with the help of drugs to reduce the swelling of the nasal mucosa or antibiotics if the infection is more serious. Remember that any toothache is one of the signs that you need to see a dentist, and he will refer you for further tests when he realizes that you do not have a dental problem.
4. You brush your teeth too hard
Because of this habit, the gums recede and become damaged. The root of the tooth then becomes more exposed to food, other 'stimuli' and bacteria, and therefore more sensitive, so you may feel pain when you drink cold drinks or eat certain foods. So forget about 'aggressive' brushing, especially if you use very hard brushes.
5. You have a cracked tooth
A tooth can crack for many reasons - from another injury, when you bite down on something hard, and in many other situations. In this case, you may feel pain when chewing food or consuming cold liquids. Although the reaction is very similar to that of caries, it is still a simpler problem and the tooth just needs to be closed properly so that the crack does not spread.
