Guided Biofilm Therapy (GBT) is a modern, pain-free treatment for effectively removing biofilm from the teeth. The process uses air, warm water, and a powder to gently and thoroughly clean the teeth. GBT is designed to be comfortable, even for those with sensitive teeth. It's also adjustable, meaning the pressure and intensity can be tailored to each patient's comfort level. While everyone's pain tolerance is different, most patients report that GBT is a painless process.
