Adult's Oral Health 

Some people think tooth decay is just for children, but did you know you are at risk your whole life? Untreated dental disease can lead to serious health problems such as infection, damage to bone or nerve and tooth loss. Dental infections that are left untreated can even spread to other parts of the body and, in very rare cases, can be life threatening.
 
Dental disease is preventable
The good news is that dental disease is preventable. You can practice preventive dentistry on yourself by adopting these healthy habits: Always remember to brush your teeth twice a day, floss between teeth once a day, eat a balanced diet and limit between-meal snacks. And don't forget to schedule regular dental visits. By following a healthy dental routine and making smart food choices, you can lower your risk for tooth decay.
