Tooth wear frequently seen with deep vertical overbites. -

Pictures of tooth damage. / Virtual makeover (before-and-after) examples showing how repairs can be made using dental crowns.

This page explains how dental crowns can be used to rebuild and restore the appearance of worn front teeth.

Each case discussed is similar by way of the fact that the type of damage that's occurred is characteristic for people who have a deep vertical overbite (see below for an explanation).

In cases like these where an extensive amount of wear has taken place, dental crowns typically make the best choice for the repair due to the great strength characteristics that they can offer.


Example #1

In this first picture you can see how the person's front teeth, especially their center two, have substantial wear.

The front teeth of this smile are extensively worn.

Case #1. (View this makeover's full-size animation.)

One reason for the extent of this damage is related to the fact that they have a deep vertical overbite.

Vertical overbites.

What we're referring to here is that when fully closed, this person's top and bottom front teeth overlap significantly.

A rough estimate of the amount involved can be gauged from the picture. With their back teeth fully closed, this person's upper teeth probably overlap about 1/2 the height of their lowers. With a "normal" occlusion, this amount would be much less.

Wear facets on teeth.

Wear facets.

If a photo could somehow be taken from the side, it would show that both the upper and lower teeth have beveled biting edges (see graphic).

That's because due to the overbite the upper and lower teeth are in frequent contact. And when they are, wear takes place on the front side of the lower teeth and the back side of the uppers. (These flat surfaces are called "wear facets.")

Front side wear on the lower teeth. Back side on the uppers.

Example A

Here's a close-up of two teeth that display a classic overbite-related wear pattern.

The beveled surface of the lower tooth matches up with a wear facet on the back side of the upper one. In this instance, both teeth have undergone a fair amount of damage.

Example B

When looking at the full-sized makeover pictures for Case #1 (the first photo we showed up above), you can just make out the wear facets on the lower teeth.

The wear on the back side of upper teeth is much more obvious (and extensive) and has resulted in the loss of massive portions of tooth structure. (Quite possibly parts the tooth had worn quite thin and then fractured off.)

 


Rebuilding the teeth using crowns.

A crown completely encases a tooth.

With teeth worn as extensively as the upper front incisors are in Case #1, dental crown placement makes the best (and possibly only) choice. (Here's our illustration of how this repair would turn out.)

The idea is that a crown cups over and encases its tooth as a whole, thus providing a way to both rebuild and strengthen it.

Vs. veneers.

In comparison, porcelain veneers, while capable of creating a similar cosmetic end result, are just bonded on to the front side of teeth. They are much more fragile in nature and do little to strengthen a tooth. (This page compares applications for veneers vs. crowns.)


Example #2

The biting edges of these teeth are very worn.

Case #2. (View this makeover's full-size animation.)

This second case shows the same type of wear pattern as Case #1.

  • On the bottom, you can see the beveling of the top portion of the incisors.
  • The ragged biting edges of the upper central incisors suggest that they have worn thin from the back side and, finally, a point has been reached where fragile bits have chipped away.

Vertical overbites.

Just as with Case #1, a prime factor in the fashion in which the wear has occurred has to do with the way the teeth come together. When closed, the upper and lower front teeth overlap significantly.

As mentioned above, this is termed having a deep vertical overbite. And in this case, the upper teeth probably overlap 50% or more of the height of the lowers. With an ideal occlusion, the amount would be significantly less.

Rebuilding the front teeth using crowns.

Our "after" picture for this case illustrates how dental crowns might be used to make a repair for this smile.

Why crowns make the best choice.

Instead of crowns, a treatment alternative for this case might be to place porcelain veneers. But as discussed above, doing so probably wouldn't provide as lasting a repair.

Just like crowns, veneers can give an excellent cosmetic result. But when they are exposed to excessive forces (like those that have worn down these teeth) they frequently chip or break.

In comparison, dental crowns are the strongest type of dental restoration that can be placed. (Use the link up above for more details about the uses of crowns vs. veneers.)

Improving the apparent alignment of the teeth.

When a crown is placed, the dentist has a chance to make significant changes with the shape of the tooth.

With this case, the crowns for the lateral incisors could be made in a fashion where their front surface is slightly fuller, thus creating the illusion of more perfect tooth alignment.

In similar fashion, crowns could be used to change (straighten) the apparent angulation of the center two teeth.

This person's front teeth, both top and bottom, show a great deal of wear. Most likely it's the result of...

a )Tooth wear - A person's malocclusion (in this case a deep vertical overbite) can place them at greater risk for tooth wear. b ) Dental crowns - As this makeover illustrates, crowns can be used to both rebuild damaged teeth and improve their apparent alignment.

a) Worn teeth - The upper teeth of this smile show wear, likely due to a habit of tooth grinding. b) Crowns - As this makeover explains, the extensive nature of this wear and resulting fragile status of the teeth means that dental crowns (and the strength characteristics they offer) would make the best choice.
