What Is Cosmetic Contouring?
Cosmetic contouring reshapes a tooth by removing a very small amount of enamel. It is also called tooth reshaping or enamel shaping.
It is the smallest cosmetic treatment we offer. Your dentist smooths an edge or a corner, and the change is visible the same day.
Most appointments take under an hour, and you rarely need an injection. Enamel has no nerve supply, so shaping it does not hurt.
What It Can Fix
- A small chip on the edge of a front tooth
- One tooth slightly longer or more pointed than the one beside it
- A corner that catches your lip or feels sharp against the tongue
- Edges worn unevenly by grinding
- A tooth that overlaps its neighbour very slightly
The common thread is that these are small differences. Contouring refines a smile that is already close.
What It Cannot Fix
There is a limit to how much enamel can come off. Take too much and the tooth becomes sensitive and weaker.
- Teeth that are noticeably crooked or crowded need orthodontic treatment
- Larger chips and gaps are better filled with bonding, which adds material rather than removing it
- Discoloured teeth are a colour problem, not a shape one
- A whole-smile change is what veneers are for
Enamel does not grow back. That is the one thing to understand before agreeing to it, and it is why your dentist takes off as little as possible.
How Much Enamel Can Be Removed?
Front teeth carry roughly half a millimetre to a millimetre of enamel to spare at the edge, and rather less at the sides.
Your dentist takes an x-ray first to see how thick the enamel is and where the pulp sits inside the tooth. Someone who has already worn their teeth down through grinding has less to give than someone with untouched edges.
If the shape you want needs more than the tooth can spare, your dentist will say so and suggest building the tooth up instead. That is a better answer than a thin, sensitive tooth.
Contouring, Bonding or Veneers?
- Contouring takes a little enamel away to reshape an edge
- Bonding adds tooth-coloured material to build a tooth up
- Veneers cover the whole front surface with a thin shell
The three are often combined. Your dentist may shape one tooth down and build the next one up, which balances a pair far better than treating either alone.
What the Appointment Involves
- Your dentist examines the teeth and checks how much enamel is available.
- An x-ray confirms the pulp is not sitting close to the surface.
- The change is marked out and agreed with you first.
- A fine instrument shapes the edge, a small amount at a time.
- The surface is polished smooth and your bite is checked.
Your dentist stops and looks in a mirror with you along the way. Small changes read very differently in the mouth than they do on paper.
Afterwards
There is no recovery period. You eat and drink normally the same day.
- Mild sensitivity to cold can last a few days and then settles
- Brush and floss as usual from that evening
- Tell your dentist if the bite feels high when you close
- Wear your night guard if grinding caused the wear in the first place
That last point decides how long the result lasts. Reshaping a worn edge without treating the grinding behind it means the wear simply returns.
How Long the Result Lasts
The reshaping itself is permanent, because enamel does not regrow. In that sense the result never wears off.
What changes over time is everything around it. Teeth keep wearing at the edges through normal use, and faster if you grind. A tooth shaped at thirty will not look identical at fifty.
Because the change cannot be reversed, it is worth being certain. Ask your dentist to show you the plan on a photograph first, and take the time to think about it.
Book a consultation if a tooth edge looks uneven or catches your lip. Bring a photo of your smile if there is something specific about it you want changed, because it makes the conversation far easier.
