Hi-

While using my sonicare, on my upper teeth, I jammed( due to my limited opening) it in the back of my left upper molars and though I left a piece of plastic break off....I went through the spit and did not feel anything hard...Then I ran my tongue over each side. I believe I broke a small piece of tooth 15 off, the mesial occlusal(?) part. This was 6 hours ago. It is now 3:49 EST, and i think I feel some pain.

Will this cause me pain? Did I damage the tooth enough to require restoration? What symptoms should I look out for?

Thanks.
Stacy
