What veneers fix well
Veneers are the right tool when the problem is the surface of the tooth.
Discoloration that doesn’t respond to whitening. Some staining is in the deeper structure of the tooth rather than the enamel, and no amount of bleaching gel will shift it. Tetracycline staining is the classic example. Whitening makes the rest of your teeth brighter and leaves the stained one looking worse by comparison.
Chips and worn edges. Front teeth wear down unevenly, and an edge that has chipped and been smoothed over the years ends up shorter than the tooth beside it.
Small gaps. A gap between the two front teeth can be closed by widening both teeth slightly, which a veneer does without moving anything.
Teeth that are the wrong shape. Narrow lateral incisors, sometimes called peg laterals, are common and are one of the situations where veneers make a dramatic difference.
Teeth that are slightly out of line. Emphasis on slightly. A tooth that sits a little forward or a little back can be masked. A tooth that is genuinely crooked cannot, and we’ll say so.
