Short answer: Some pharmacies and stores carry ready-made night guards in standard sizes or boil-and-bite versions. These products temporarily separate the teeth with an intermediate layer, but they are not made from an impression of your mouth, and the bite balance is not adjusted. They may be an option for short-term use; long-term use, the type of guard and whether it is made for the upper or lower jaw are determined at a dental examination.
For many people who notice teeth clenching or grinding, the first question that comes to mind is whether night guards are sold in pharmacies. In short, yes: some pharmacies and stores carry ready-made mouth guards produced in standard sizes. However, whether a ready-made guard suits your teeth, your bite and the condition of your jaw joint can only be understood through an oral examination. In this article, we take a measured look at what ready-made guards are, how they differ from custom guards, when they may be considered as a short-term option, and which jaw a guard is made for.
What is an over-the-counter night guard sold in pharmacies?
An over-the-counter night guard sold in pharmacies is a tooth guard or mouth guard mass-produced without taking an impression of the person's mouth, usually made from thermoplastic material. These products fall roughly into two groups:
- Standard (stock) guards: Made in a single mold and worn as they are. How they sit in the mouth varies markedly from person to person.
- Boil-and-bite guards: The material is softened in hot water and placed in the mouth, and the person gives the guard a rough shape by gently pressing their teeth into it. This method is popularly known as "boil and bite".
The basic aim of both types is to create an intermediate layer that reduces direct rubbing of the teeth against each other. Sports mouth guards are made on a similar principle; however, in sports the concern is impact protection, while nighttime use involves clenching forces lasting for hours. That is why it should not be assumed that the same material will behave in the same way for two different purposes.
The practical answer to where night guards are sold is this: ready-made products can be found in pharmacies, medical supply stores and online, while a custom guard is made in a laboratory from an impression taken after a dental examination. For general information, you can also take a look at our dental guard page.
Differences between ready-made and custom guards
The key difference between a ready-made guard and a custom guard is how well the guard matches the teeth and the bite. This can be summarized under a few headings:
- Fit and retention: Because a custom guard is made from an impression or digital scan of the teeth, it surrounds the teeth more evenly. A ready-made guard, being produced for an average mouth, may leave gaps in some areas and create pressure in others.
- Bite balance: With custom hard guards, the dentist can adjust the guard so that the lower and upper teeth contact it evenly. This adjustment cannot be made on a ready-made guard; contact points may form at random.
- Thickness and material: Ready-made guards are mostly made of thicker, softer material. With custom guards, thickness and hardness are chosen based on the complaints and examination findings. For details on the types, see our article explaining the difference between hard guards, soft guards and splints.
- Follow-up: A custom guard is assessed for wear and fit at follow-up visits. With a ready-made guard, this monitoring is left to the person.
- Comfort: A thick, bulky design can make some people feel that it takes up too much room in the mouth, increase saliva or make it harder to fall asleep. This varies from person to person.
These differences do not mean ready-made guards are "unusable"; they simply show that expectations need to be set correctly according to the purpose and the person's mouth structure.
Who might a ready-made guard be a short-term option for?
A ready-made night guard may be considered as a temporary option for the short period until a dental examination, or in limited situations the dentist considers suitable. For example:
- People who have just noticed a clenching complaint and want to protect their teeth until their appointment date,
- People who cannot keep their custom guard with them in temporary situations such as travel and who have received advice on this from their dentist,
- Adults who have no extensive restorations, bridges, implant-supported prostheses or removable dentures in the mouth and no significant jaw joint complaints.
On the other hand, if you have complaints such as jaw pain in the morning, catching when opening the mouth, joint noise or headaches, it is more appropriate to be examined first rather than choosing a guard on your own. Such findings may be related to the jaw joint, and the guard type needs to be determined at an examination. We have described the possible causes of teeth clenching in our article on the causes of bruxism and treatment methods.
If, after starting to use a ready-made guard, you notice tooth sensitivity, a sense of change in your bite, gum irritation or jaw fatigue, it is recommended that you pause its use and consult your dentist. You can find more about possible side effects in the article on night guard side effects.
Is a night guard made for the upper or the lower jaw?
There is no single correct answer to whether a night guard goes on the upper or the lower jaw; which jaw it is made for is determined at the examination based on the person's tooth alignment, bite and complaints. In practice, hard night guards are often made for the upper jaw, but there are also a considerable number of cases in which a lower guard is preferred.
When might an upper guard be preferred?
The upper jaw usually offers a wider and more stable area for retention. That is why the upper jaw is a commonly used option for hard guards whose bite is adjusted. The aim is for the lower teeth to contact the flat surface of the guard evenly.
When might a lower guard be preferred?
People with a pronounced gag reflex, or who find a structure close to the palate uncomfortable, may tolerate a lower guard more easily. Being less noticeable when speaking is also a reason some people prefer it. A lower guard may also be considered if there is a newly made prosthesis or ongoing treatment in the upper jaw.
In short, the question of which jaw a night guard is made for is assessed together with the type of guard. With ready-made guards, this choice is usually left to the user, which means the bite balance cannot be checked.
Can you wear a ready-made guard with braces or clear aligners?
Using a ready-made night guard during orthodontic treatment is generally not recommended; the decision rests with the orthodontist managing the treatment. With braces in place, brackets and wires can prevent a ready-made guard from fitting, and the guard can press on the wires. In addition, because the teeth move throughout treatment, a guard that has been shaped once may stop fitting within a few weeks.
The situation is somewhat different with clear aligner treatment. Because clear aligners such as Invisalign are also worn at night, some patients already have a thin protective layer over their teeth. That is why wearing an additional ready-made guard is unnecessary in most cases and can also disrupt how the aligners fit. For patients with clenching complaints, the orthodontist assesses aligner wear and fit at check-ups and makes a separate plan if necessary. For general information on clear aligner treatment, see our clear aligner treatment page.
The retainer used after treatment is complete and a night guard are not the same product either. We discussed this distinction in our article can a night guard straighten teeth.
How is a custom guard made?
A custom night guard is made by going through the stages of examination, impression or digital scan, laboratory production and fitting in the mouth. The process usually proceeds as follows:
- Examination: The dentist assesses tooth wear, gum condition, the jaw muscles and the jaw joint. Whether the complaints are related to clenching and whether a guard is needed are determined at this stage.
- Impression or scan: Impressions of the lower and upper teeth are taken with the conventional method or an intraoral scanner, and a bite registration is made if necessary.
- Production: The guard is made in the laboratory according to the selected material.
- Delivery and fitting: The guard is tried in the mouth; with hard guards, contact points are checked and adjusted if necessary.
- Check-ups: During use, the guard's wear, fit and changes in complaints are monitored.
The production stages and when the guard should be replaced are explained in detail in the article on how a teeth-clenching guard is made, cared for and replaced. For daily use and cleaning of the guard, you can read our night guard use and cleaning guide. As for the fee, because it varies with the type of guard and the person's needs, it is provided in writing after the examination and planning.

Frequently asked questions
Are night guards sold in pharmacies?
Some pharmacies and medical supply stores carry ready-made mouth guards in standard sizes. These products are not made from an impression of your mouth. If long-term use is being considered, a dental examination is recommended first.
Does a boil-and-bite guard replace a custom guard?
A boil-and-bite guard roughly fits the teeth, but the bite balance is not adjusted by a dentist. That is why in most cases it does not replace a custom guard. Whether it is suitable for short-term use is assessed at an examination.
Which jaw is a night guard worn on?
Hard night guards are often made for the upper jaw, but lower guards are also widely used. The dentist makes the choice based on factors such as tooth alignment, the bite, the gag reflex and existing prostheses.
What should I watch out for when using a ready-made guard?
The guard should fit without pressing on the teeth, should not create a sense of change in your bite and should not irritate the gums. If you notice sensitivity, jaw fatigue or pain, it is recommended that you pause its use and consult your dentist.
Do I also need a night guard during clear aligner treatment?
Because clear aligners are also worn at night, a separate night guard is not needed in most cases. For patients with clenching complaints, the orthodontist assesses aligner wear at check-ups and makes an additional plan if necessary.
