Prevent Dental Emergencies
Most dental emergencies are preventable. These six habits dramatically reduce your risk.
Wear a Mouthguard
Always wear a properly fitted mouthguard during contact sports. Custom guards from your dentist offer the best protection.
Don't Use Teeth as Tools
Never use your teeth to open packages, bottles, or cut tape. This is a leading cause of chipped and cracked teeth.
Regular Check-Ups
Biannual dental exams catch problems early — before they become emergencies. Many emergencies are preventable with routine care.
Address Pain Early
Tooth pain is your body's warning signal. Don't ignore it. A small cavity treated early avoids a root canal or extraction later.
Build a Dental Emergency Kit
Keep dental wax, gauze, OTC pain reliever, dental cement, and your dentist's after-hours number in a small kit at home.
Know Your Dentist's After-Hours Line
Ask your regular dentist for their emergency contact number. Many practices have after-hours lines or on-call coverage.
When to Go to the Emergency Room
Some dental situations require an ER, not a dentist.
