Tooth decay is another word for cavity. Preventing cavities depends on what you eat and how you take care of your teeth. It is also best to see your dentist regularly. The amount of fluoride in toothpaste used will help to prevent cavities. Some teeth problems are hereditary. No matter how much you take care of your teeth you may still have teeth problems, but don't stop trying. Try to avoid soda and foods with a lot of sugar. Make sure to visit your dentist every six months. This will help even the person who has inherited teeth problems to reduce the risk of cavities.

Dry mouth can be inherited and can cause cavities. People who have this problem don't have enough saliva in their mouth. This problem is also commonly caused by illness or medications. Radiation treatment can also cause this problem. Tobacco use causes this problem and causes many cavities. The tobacco uses all the saliva in the user's mouth so there is none left to keep the mouth moist. 

If cavities are left untreated the tooth will decay. The infection can spread to other teeth, gums and other areas in the mouth. The nerves can also be destroyed in the tooth which leads to abscess. An abscess infects the root tip. This is very serious. If left untreated and abscess can cause death. 

Regular visits to the dentist are needs to prevent cavities. A cavity starts small and can not be detected by human eye at first. The dentist has tools that can find the cavity before it gets too big. Most cavities develop below the gums which is why it is impossible to see them. When the cavity reaches the tooth you will see it because the color will change in the infected area. If you notice a color change or blackened area in your tooth, make an appointment with your dentist immediately. 

What you eat or drink affects your teeth in a good or bad way. If you drink a lot of carbonated drinks or sugary drinks you will have more cavities. If you eat unhealthy foods or foods with a lot of sugar you will have cavities. Foods that are rich in sugar and starch are eaten by bacteria found in plaque. This will produce acids that eat through the dentin and enamel very quickly. If you don't visit your dentist quickly the acid will continue eating the tooth until there is nothing left. Then you will have to get the tooth extracted. Over time the tooth enamel will break down beneath the surface of the tooth even though the surface will appear fine for a while. Once the acid eats the enamel away, the surface will collapse which results in a cavity. This will be very painful and dangerous if not treated. Most cavities can be found in the pits of chewing areas around your teeth, in the back and in between the teeth or near the gum line. 

Most people will have at least one cavity in their life. The best way to be sure you don't have cavities or lose all your teeth is to follow these simple steps. Brush your teeth with a toothpaste with fluoride no more than twice a day, usually when you get up and before going to sleep at night. Be sure to avoid eating a lot of junk food with sugar and starch. In other words, try to eat healthy. Visit your dentist on a regular basis. The dentist is your friend, not your enemy. Taking care of your teeth is a great way to help you look younger and healthier.
