It is relatively simple. The thing to remember is excellent oral hygiene. This means brushing twice each day, flossing daily, and using a special interdental cleaner when necessary. You should also visit us on a regular basis to get your teeth and mouth checked, and have a professional cleaning.
Avoid tobacco, which can darken your new smile. Eliminate hard foods like ice or hard candy from your diet, since they can potentially harm your dental work. Avoid grinding your teeth. If you find this habit impossible to break, consult me about neuromuscular dentistry.
The best way to keep your smile looking great is to keep smiling, because that will motivate you to be diligent about your dental health.
