I've had my top front 8 teeth veneered for 4.5 years. I am a light grinder and wear a mouth guard. My dentist says I have great oral hygiene and healthy gums. Lately I've noticed a moving sensation with 3 of my veneered teeth when I eat. I can even hear them click. They feel like they're moving for several minutes after I'm done eating. Is it possible for food to get under the veneer? Or is my entire tooth moving? My dentist has never heard of this and didn't notice any movement at my last appt.
