What causes bad teeth?

The first thing people do when they wake up every morning is to brush their teeth, because there will be some bad smell in the mouth after getting up in the morning. Although we brush our teeth every morning and evening, the bacteria in the teeth cannot be completely eliminated, so it will cause bad smell between teeth. Generally, this smell cannot be smelled at ordinary times. Only when picking teeth, the food residue in the teeth will have this smell. Therefore, we should rinse our mouths more often to ensure oral hygiene.

Everyone has bad breath when they wake up in the morning. The mouth is an open environment, and even if you brush your teeth very clean, there will still be some bacteria remaining in your mouth. These bacteria move around in the mouth, ferment proteins, and produce indole (body odor), hydrogen sulfide (fart smell), and ammonia (toilet smell), making the breath unfresh. Especially when sleeping at night, the secretion of saliva, the "policeman" that can flush teeth and inhibit bacterial activity, is significantly reduced, while the concentration of "valuable goods" - protein will increase accordingly. You can imagine how active the bacteria activities will be at night and how high the crime rate will be.

Bad breath that won't go away or a persistent bad taste in the mouth can be a warning sign of advanced periodontal disease, which is often caused by plaque, a sticky, cavity-causing buildup of bacteria. Usually, dental plaque comes first and then tartar! There are four factors that form tartar: one is food residue, two is saliva environment, three is bacteria, and four is a long time. Most of them grow on the edge of the gums. Some people have too much tartar and feel that their teeth are going to break when washing their teeth. But tartar does not only grow on the gums. Patients with periodontitis will also have tartar under the gums. Frequent bleeding when brushing your teeth may be caused by tartar. .

Food residues ferment in the oral environment and react with bacteria to decompose an enzyme, forming a gas that smells like rotten eggs. The larger the dental plaque is, the more severe the bad breath will be. If you do not brush your teeth before going to bed for a long time, you will find that the dental plaque is slowly hardening because dental plaque quickly thickens in 1 to 2 hours. If you do not brush your teeth for more than 10 nights, the dental plaque and teeth are probably integrated. Usually, be careful not to eat hard food to avoid periodontal trauma, and do not eat too cold, hot, sour or sweet food to avoid causing dentin allergy symptoms. Under normal circumstances, everyone needs to have a dental cleaning every six months to a year, because the bacteria in the mouth accumulate on the surface of the teeth to form dental plaque. Dental plaque not only corrodes the teeth and causes caries, but also gradually calcifies to form calculus, which compresses the gums and causes them to recede. The mechanical stimulation of calculus and the inflammatory stimulation of bacteria cause bleeding, red and swollen gums. This is gingivitis. If not treated in time, the inflammation will slowly erode the alveolar bone and cause periodontal disease, leading to periodontal atrophy, loose teeth, and finally tooth loss. Smoking can stain teeth, cause bad breath, and expose people to a host of health risks. Tobacco reduces people's ability to taste food and irritates gum tissue; people who smoke are more likely to suffer from gum disease. Because smoking also affects a person's sense of smell, smokers may not be aware of the smell of their exhaled gas.
