While over-the-counter mouthguards are sometimes better than nothing, they’re not as effective as custom-fit models. Additionally, a poorly designed mouthguard or oral appliance can cause discomfort, pain, and damage to your teeth and gums. If a mouthguard is too loose, it can slip and fail to provide proper protection. If it's too tight, it can put too much pressure on your teeth and cause them to shift or crack.
An improperly designed oral appliance can also cause pain and discomfort in the jaw, head, neck, and shoulders and lead to dental problems down the road. That's why it's crucial to choose a custom-made mouthguard or oral appliance from a reputable dental practice to ensure maximum comfort, protection, and effectiveness.
