If you grind your teeth, a nightguard can save you from a lot of damage and discomfort. But once you start shopping, you will find two very different options: an affordable guard from the drugstore, or a custom one made by your dentist.
At Valley Dental Turlock, patients often ask whether the store-bought version is good enough. Here is an honest comparison so you can decide what is right for you and your nightguard needs.
How store-bought nightguards work
Over-the-counter guards come in two main styles: a one-size-fits-all stock guard and a boil-and-bite version you soften in hot water and press onto your teeth. They are inexpensive and available right away, which makes them appealing. The trade-off is fit. Because they are not made to your exact bite, they can feel bulky, slip during the night, or fail to cover your teeth evenly, which limits how well they protect.
How custom nightguards work
A custom nightguard is made from a precise impression or digital scan of your teeth, so it fits snugly and comfortably. Because it is shaped to your unique bite, it stays in place, distributes pressure evenly, and uses higher-quality materials built to last. Many patients find a custom guard so comfortable that they forget they are wearing it, which makes them far more likely to use it every night.
Comparing the two
- Fit: Custom guards are tailored to your bite; store-bought guards are generic.
- Comfort: Custom guards tend to be slimmer and more comfortable, so they are easier to wear nightly.
- Protection: A precise fit gives more reliable protection against grinding and clenching.
- Durability: Custom guards use stronger materials and generally last longer.
- Cost: Store-bought guards cost less up front; custom guards are a larger investment that often pays off in durability and protection.
What getting a custom guard is like
If you have only ever shopped for a drugstore guard, the custom process is simpler than you might expect. At your visit, we capture the shape of your teeth, either with a quick digital scan or a soft impression material, and Dr. Tannaz Ahmadi notes how your upper and lower teeth come together. That information goes to a dental lab, where your guard is built to your exact bite from durable material. When it is ready, you return so we can check the fit, make any small adjustments, and show you how to wear and care for it. The result is a guard that seats securely and feels far less bulky than a one-size-fits-all version, which is a big reason custom guards actually get worn night after night.
Which one is right for you?
A drugstore guard can be a reasonable short-term option if you want to try something quickly while you wait for a custom one or want to see whether wearing a guard helps at all. For lasting comfort, reliable protection, and the best fit, a custom guard from your dentist is usually the better long-term choice, especially if you grind heavily, already have worn teeth, or have crowns and other dental work to protect. A poorly fitting store guard can even shift your bite or fall out during sleep, which defeats the purpose. If you are unsure, request an appointment at Valley Dental Turlock, and we will review your bite and explain financing options to help you decide. You are also welcome to meet Dr. Tannaz Ahmadi and ask questions before committing.
