Many dentists prefer to practice preventive dentistry over restorative dentistry because it is much easier to prevent a problem from happening than treating it. The main form of preventative dentistry that everybody should be practicing is brushing your teeth twice a day or after every meal. You should also floss your teeth at least once a day to remove bacteria and food particles that get caught between the teeth and gum line.
As important as daily oral hygiene maintenance should be to your routine, you should also schedule dental examinations with your dentist once every six months. A professional dental cleaning is much more effective at removing bacteria than brushing and flossing on your own. The dentist also uses this time to take dental X-rays in order to see if any problems are developing in areas that cannot be seen. The dentist will ask you questions about your diet and lifestyle to see if any recommendations can be made to improve your dental health.
If brushing and flossing do not appear to be enough, you can also be given a fluoride treatment to strengthen your enamel. You may also be given dental sealants to be applied over the fissures of your tooth so that bacteria has less space to build up.
