Why Your Smile Makeovers Fail: The Occlusion Mistakes No One Talks About
Written by Dr. Agatha Bis
Smile makeovers are supposed to be the crown jewel of cosmetic dentistry. Patients walk in with worn, stained, or misaligned teeth, and walk out with the smile of their dreams. At least, that is the idea.
But what happens when that dream smile turns into a nightmare?
You followed the protocols. The veneers looked perfect. Margins were clean. Shade match was ideal. But then…
The patient returns with chipped ceramics.
They say their bite feels off.
There is a black line at the margins.
They develop sensitivity, or worse, TMJ symptoms they never had before.
You start to wonder: What went wrong?
It is Not the Veneers, It is the Bite
The truth is, most cosmetic failures are not because of the lab work. They are not about bonding technique or material selection. They are about occlusion, and the functional mistakes we were never taught to think about in aesthetic training.
Here is what no one tells you. A smile that looks great on day one can collapse in six months if you ignore how the teeth come together, how the joint is functioning, and how force is distributed across the system.
Three Occlusion Mistakes That Ruin Cosmetic Cases
1. Skipping the Functional Risk Assessment
If you are jumping into smile design without first asking: Is this patient functionally stable?, you are gambling with the outcome.
Look for:
Wear facets or flattened incisal edges
TMJ clicks or joint tenderness
A scalloped tongue or linea alba as signs of parafunction
Bite changes or history of multiple occlusal adjustments
These are signs the system is unstable, and locking in a new bite with veneers will only make it worse.
2. Ignoring Anterior Guidance
The front teeth do not create the smile, they protect the back teeth. If you restore aesthetics without respecting anterior guidance, you are asking for posterior overload, fractures, and even TMJ pain.
And let us be honest. Many patients seeking cosmetic dentistry already have worn front teeth. That wear means something. If you do not rebuild guidance, you are restoring aesthetics on top of dysfunction.
3. Designing for Looks, Not Function
Too often, we prep and place based on smile line, width, and symmetry, but ignore function, interferences, contacts, or where the mandible wants to be.
So what happens? The restorations interfere. The bite shifts. The joints absorb the tension. Your perfect case starts to fall apart.
So How Do You Prevent It?
You slow down. You assess first. You understand that cosmetic success starts with functional stability.
Here is where to begin:
Screen every patient for joint and muscle symptoms. Do not assume no pain means no dysfunction.
Evaluate occlusion before you prep. Use a deprogrammer or leaf gauge if TMJ is healthy. Use an orthotic if TMJ is not healthy in order to reveal true bite position.
Rebuild anterior guidance and posterior support together. You cannot restore aesthetics without also restoring protection.
Use functional provisionals when in doubt. Test the bite and the aesthetics before you commit to final restorations.
Know when to delay treatment. Some patients need orthotic therapy or stabilization first. You are not saying no. You are saying not yet.
Final Thoughts
Cosmetic dentistry is about more than pretty smiles. It is about creating smiles that last, that feel good, and that support long-term oral health.
If your smile makeovers are failing, or you want to prevent them from failing in the future, start by thinking beyond the enamel. Look at the joints. Look at the muscles. Look at the forces you are locking in.
Because beauty fades fast when it is built on dysfunction.
