Shredding floss could be a sign of a broken filling, crowded teeth, leftover material from a new filling or crown, or decay under an existing filling or crown.
First, try a thinner floss or waxed floss. However, if the problem continues, call Lakeshore Dental, or make sure to mention it during your next scheduled exam. It could be a simple adjustment to the way your teeth touch, or the need to replace an existing filling or a crown. If crowding is the issue, braces may be recommended. Of course, our hygienists are always happy to help you with your flossing technique.
