Believe it or not, teeth have memory. This means that after orthodontic treatment, if you don't regularly wear a retainer, your teeth will gradually shift back into their previous position.
If you have an old retainer that you haven't worn in a while, it may no longer fit properly due to drifting. If it's an old retainer that you've been regularly wearing, your dentist can help you decide if it's still serving the purpose and keeping your teeth protected and aligned properly.
Glendale dentist, Dr. Lucio Kim, may also recommend a nightguard if you suffer from bruxism (teeth grinding or clenching) at night. This is an appliance that fits over your teeth, much like a retainer, to protect them from the clenching and grinding that sometimes takes place while you sleep.
Bruxism can prematurely wear your teeth down, and it can also result in painful jaw joint problems. A nightguard protects your teeth while helping you to sleep comfortably at night.
The best way to determine if you have a viable retainer, or if you need a nightguard is to schedule an examination with Dr. Kim. He can recommend the best appliance to protect your teeth and help you meet your smile goals. Contact our Glendale dental office at (818) 242-3739 for more information.
