- A custom dental mouth guard is molded to your exact bite, so it usually fits better and protects more reliably than a one-size store-bought version.
- Mouth guards are commonly used for teeth grinding and clenching (bruxism), for sports, and sometimes to help with jaw-related discomfort.
- Grinding often happens during sleep, so many people do not realize they do it until a dentist spots the wear or a partner hears it.
- Our South San Francisco office can design night guards in-house using SprintRay 3D printing for a precise, comfortable fit.
- With simple cleaning and storage, a quality custom guard can often last for years.
A custom-fitted dental mouth guard is a thin, durable appliance that cushions and protects your teeth from grinding, clenching, or sports impact — molded precisely to your bite for better protection than store-bought versions. At Vaksman Dental Group in South San Francisco, our dental team can take a quick digital scan of your teeth and craft a guard made just for you, serving patients across South San Francisco, San Bruno, Daly City, and nearby Peninsula communities.
What Is a Dental Mouth Guard?
A dental mouth guard is a custom-made cover that fits over your upper or lower teeth. Because it is shaped from a precise model of your own mouth, it tends to stay in place better and feel more comfortable than the boil-and-bite kits sold at the drugstore.
There are a few common types, and your dentist can help you choose the right one:
- Night guards — worn while you sleep to protect teeth from grinding and clenching.
- Sports mouth guards — worn during athletics to help absorb impact to the teeth, lips, and jaw.
- Bite splints — sometimes used to help manage jaw-muscle tension or discomfort.
Who Can Benefit From a Mouth Guard?
A mouth guard may be a good fit if you:
- Grind or clench your teeth, especially at night (a habit known as bruxism).
- Wake up with jaw soreness, headaches, or sensitive teeth.
- Notice flattened, chipped, or worn-down teeth.
- Play contact or high-impact sports such as basketball, soccer, or martial arts.
Grinding often happens during sleep, so many people do not realize it is happening. According to the American Dental Association’s MouthHealthy, untreated grinding can wear down enamel over time and contribute to tooth sensitivity and jaw discomfort. The American Dental Association also notes that a properly fitted athletic mouth guard can help reduce the risk of dental injuries during sports.
How It Works: What to Expect
Getting a custom guard is straightforward and comfortable. Here is the typical process at our office:
- Exam and discussion. Your dentist checks for signs of wear, clenching, or jaw strain and asks about your symptoms and goals.
- Digital scan or impression. We capture a detailed model of your teeth — often with a quick digital scan, so there is no messy putty.
- Custom fabrication. Your guard is built to your bite. In many cases we can 3D-print night guards in-house using our SprintRay system for a precise, same-practice fit.
- Fit and adjust. You try the finished guard, and we fine-tune it so it feels secure and comfortable.
Most people adjust to wearing a night guard within a few nights. It may feel a little unfamiliar at first, which is completely normal.
Benefits of a Custom Mouth Guard
A guard made for your mouth offers advantages a generic version often cannot match:
- Helps shield enamel from the steady wear of grinding and clenching.
- May ease morning jaw soreness, tension, and grinding-related headaches.
- Can help protect existing dental work, such as crowns and fillings.
- Fits snugly, so it tends to stay put and let you breathe and speak more easily.
- For athletes, helps cushion impact to teeth and soft tissues.
How Much Does a Mouth Guard Cost?
Costs vary based on the type of guard, the material, and your dental coverage. As a general national reference — these are general figures, not our office’s prices — a custom night guard often ranges from about $300 to $800, while custom sports guards are typically lower. Over-the-counter options cost less up front but generally wear out faster and fit less precisely.
We are happy to review your options and any insurance benefits before you decide. A custom guard is often a smaller investment than repairing teeth that have been worn or cracked by long-term grinding.
Caring for Your Mouth Guard
A little daily care keeps your guard fresh and helps it last:
- Rinse it before and after each use, and brush it gently with a soft toothbrush.
- Let it dry fully, then store it in its ventilated case — away from heat, which can warp it.
- Keep it away from pets, who often mistake guards for chew toys.
- Bring it to your checkups so your dentist can inspect the fit and condition.
With consistent care, a quality custom guard can often last for years. If it cracks, loosens, or starts to feel off, let us know so we can check it.

Frequently Asked Questions
How do I know if I grind my teeth at night?
Common signs include morning jaw soreness, frequent headaches, tooth sensitivity, and flattened or chipped teeth. A partner may also hear grinding sounds during sleep. If you notice any of these, your dentist can check for the telltale wear patterns and let you know whether a night guard may help.
Is a custom mouth guard really better than a store-bought one?
A custom guard is molded to your exact bite, so it typically fits more securely and comfortably and offers more reliable protection. Over-the-counter guards can be a short-term option, but they often feel bulky, fit loosely, and wear out faster.
How long does it take to get used to wearing a night guard?
Most people adjust within a few nights. It may feel slightly unfamiliar at first, which is normal. If it still feels uncomfortable after a couple of weeks, we can adjust the fit so it works better for you.
Can children and teen athletes use mouth guards?
Yes. A properly fitted sports mouth guard can help protect young athletes’ teeth during contact and high-impact activities. Because growing mouths change, we check the fit regularly and update the guard as needed.
