Although the material used for your dental implants is very tough and designed for normal function, take note that there are things you may bite on that will be harder than the materials your implants are made from. We advise our patients to avoid popcorn kernels, hard nuts, hard candies, hard pretzels, ice, and other foods that require crushing. Because your dental implants will feel like your natural teeth, it may be easy to forget, and sometimes damage may occur. Fortunately, dental implants are easy and inexpensive to repair in the office for roughly the same cost as a normal filling.
