The long version
In one sentence
A healthy tooth is not a solid block. Enamel and the softer dentin underneath work together, flexing slightly every time you bite. When a repair ignores that and simply caps the tooth in something rigid, the tooth underneath keeps flexing against it, and eventually something gives.
Biomimetic simply means imitating life. In practice it means we remove only what is actually damaged, then bond the tooth back together in layers that flex the way the original did. Less comes out, more stays in, and the repair is working with the tooth instead of against it.
Why the first decision matters
That is roughly how much of a tooth is removed to place a full crown.
Not the decay. The tooth itself. A crown needs the whole thing reduced to a peg before it can go on. Once that structure is gone, it does not come back, and every option afterward is a smaller one.

How an appointment actually goes
Under high magnification we can see precisely where healthy tooth ends and decay begins. A great deal of what looks alarming on an x-ray turns out to be smaller and more repairable than it appeared.
Staining dyes make decayed tissue visible, so we can take out what has to go and stop there. The sound structure underneath stays exactly where it is.
The tooth is bonded back together in thin increments, each one cured before the next. That builds a seal strong enough to hold and flexible enough to move with your bite.
The honest trade-off
Layering and bonding a tooth properly cannot be rushed, and a visit here will usually run longer than the same appointment somewhere else. We would rather book the extra time than take the shortcut that costs you the tooth a decade from now.
Not every tooth can be saved this way. Some are too far gone, and when that is the case we will tell you plainly rather than attempt something that will not hold. But that is a much smaller group of teeth than most people are led to believe.
Book a Second OpinionCommon questions
No. Nothing already done can be undone, but every tooth from here forward is a fresh decision. Plenty of patients come to us mid-way through that sequence and simply stop it where it is.
Yes, and we are glad to give one. Bring your x-rays if you have them. Sometimes we agree that a crown is the right call, but often enough there is a way to keep more of the tooth, and it costs you nothing to find out.
Not at all. This page exists for people who like to know the reasoning. Everyone else can simply come in, and we will walk through your options one at a time.
