My dentist recommended a night guard — do I have to get one?
A night guard recommendation is worth understanding before you decide. Learn what your dentist may be seeing, how to ask the right questions, and your options for custom versus over-the-counter guards.

Why Your Dentist May Have Recommended a Night Guard
Your dentist can see things in your mouth you might not notice yourself. During your exam, they may have spotted:
- Worn or flattened tooth surfaces. Over time, grinding or clenching wears down enamel and the structure underneath.
- Cracks or chips in your teeth. Repeated pressure, especially at night, can cause damage.
- Jaw soreness or stiffness in the morning. This often signals clenching or tension during sleep.
If your dentist mentioned any of these signs, a night guard may help prevent further wear or damage. But a recommendation is not a requirement — it’s an option to explore with your dentist.
Ask Your Dentist to Explain Their Reasoning
You have every right to understand why they suggested it. A good conversation might sound like this:
- “What wear or damage did you see that led to this recommendation?”
- “Will a night guard prevent the problem from getting worse, or address something that’s already there?”
- “Do you recommend a custom guard or an over-the-counter one for my situation?”
- “How long will it take to get used to wearing one?”
Your dentist’s answers help you decide whether a night guard fits your needs and budget. If you’re unsure, you can always ask for a second opinion from another dentist in the MediMouth network.
Custom Night Guards vs. Over-the-Counter Options
Custom night guards are made from impressions of your teeth and mouth. Your dentist sends those impressions to a lab, which fabricates a guard fitted to your bite and tooth contours. Custom guards typically last longer and feel more comfortable for nightly wear.
Over-the-counter night guards come in generic sizes and are often “boil and bite” — you soften them in hot water and mold them to your teeth. They’re easier to buy and try but may not fit as precisely.
Ask your dentist which route they recommend for you. If they suggest custom, they can tell you what to expect in terms of turnaround time and care instructions. If over-the-counter is appropriate, they can point you toward reputable options.
You’re Not Obligated — But Think About the Long Term
No one can force you to wear a night guard. However, if your dentist observed wear, cracks, or jaw soreness, ignoring the recommendation might lead to more expensive dental work down the road. On the other hand, if you’re skeptical, it’s fair to ask:
- “What could happen if I don’t use a night guard?”
- “How quickly might further damage occur?”
- “Can I try an over-the-counter option first to see if wearing one helps?”
These questions help you weigh the pros and cons for your situation.

Frequently asked questions
What does a night guard actually do?
A night guard is a removable appliance that sits over your upper or lower teeth while you sleep. It acts as a barrier to protect teeth from wear, cracks, or pressure caused by clenching or grinding. It may also help reduce jaw tension or soreness you notice when you wake up.
Is a custom night guard better than one from the drugstore?
That depends on your situation and what your dentist observed. Custom guards are made from impressions of your mouth and fit only you; over-the-counter guards are generic. Your dentist can help you weigh fit, durability, and comfort for your specific needs. Ask your dentist which option aligns with their recommendation.
What questions should I ask my dentist before buying a night guard?
Ask why they recommended it (worn spots, cracks, jaw soreness?), whether they recommend custom or over-the-counter, how often to wear it, how to clean and store it, and what to do if it becomes uncomfortable. Understanding their reasoning helps you make an informed choice.
