A veneer covers the front surface
A veneer is a thin restoration placed over the visible front of a tooth. It may be considered for selected concerns about shape, color or small defects. The dentist checks the enamel, bite, gums and any existing restorations before recommending it.
Preparation can involve permanently removing tooth structure. Ask how much preparation is proposed and whether bonding, whitening or orthodontic treatment could achieve your goal with a different approach.
A crown provides broader coverage
A crown covers more of the tooth and may be recommended when a tooth is weakened, heavily restored or needs protection after certain treatments. A crown can also form part of a bridge or restore an implant.
The amount of healthy tooth remaining, cracks, the bite and the location of the tooth matter more than appearance alone. Ask why broader coverage is needed and how the tooth will be protected between visits.
Compare the complete plan
Discuss materials, shade, expected visits, maintenance and the possibility of future repair or replacement. Existing restorations do not whiten in the same way as natural teeth, which can affect treatment sequencing.
Neither option eliminates the need to brush, clean between teeth and attend dental visits. Tell the dentist about clenching or grinding and ask whether additional protection is appropriate. A consultation can help distinguish a cosmetic goal from a tooth that needs restorative care.
