Night guards can be picked up from a local pharmacy, which would be a one-size-fits-all or a boil-and-bite type. They do the job of protecting the teeth alright but have other drawbacks. They wouldn’t offer the right fit, making them quite uncomfortable to use. With regular use, they could cause an inflammation of the gums and even bring about a change in the alignment of the teeth. Though customized night guards cost more, they would be worth the investment as they offer seamless comfort and protection.
