Yes, it's generally normal for your top teeth to cover your bottom teeth slightly when you close your mouth. However, the extent to which they cover matters.
Here's a breakdown of what's considered normal and when it might indicate a problem:
-
Normal Overbite: Ideally, your top teeth should overlap your bottom teeth by about one-half to two-thirds of the height of your bottom teeth. This slight overlap is called an overbite.
-
Deep Bite (Excessive Overbite): If your top teeth cover significantly more than two-thirds of your bottom teeth, you might have a deep bite. This is also sometimes called an overbite, but it refers to an excessive overbite, and is considered a malocclusion.
-
Open Bite: Conversely, if your top teeth don't overlap your bottom teeth enough (or at all), you might have an open bite.
What to Do If You Suspect a Problem:
If you are concerned about how much your top teeth cover your bottom teeth, it is best to consult with a dentist or orthodontist. They can properly assess your bite and recommend appropriate treatment options if necessary.
In summary: A slight overlap of your top teeth over your bottom teeth is normal. Too much or too little overlap may indicate a bite issue that requires professional evaluation.
