Teeth need as much care as the human body. generally speaking, at age 30: enamel thins and teeth begin to discolor. at age 40: the dental bed begins to shrink and teeth begin to loosen slightly, causing deformation and gaps. at age 50: teeth become brittle and susceptible to infection and damage. If you do not develop good dental care habits, it will be more likely to be damaged. 1. How to prevent toothbed recession To keep your teeth in a healthy condition, have your teeth cleaned twice a year and ask your dentist for a comprehensive check-up. Keeping your teeth free of tar and bacteria will keep your dental bed strong and flexible without shrinking. Another important point to note is that regardless of age, make sure you choose the right toothbrush and dental floss to remove tartar. Ask your dentist to check if you are brushing your teeth the right way. If you brush back and forth instead of rotating your teeth, you may be prematurely receding your dental bed. Another preventive measure is to massage your dental bed daily. 2. Teeth grinding and teeth whitening There are a variety of options available to make teeth younger and healthier. If your teeth appear to be unevenly worn, consider grinding them. This is where the edges of the teeth are polished to make them more attractive. If your teeth have become discolored, ask your dentist about cold light whitening, which can be used to brighten your teeth. If there are gaps in your teeth, they can also be improved on the inlay.
