Veneers or bonding: how the decision is actually made

People usually arrive having decided which treatment they want, and the consultation is often spent gently unpicking that. The right answer depends on how much tooth structure is already missing, how much colour change is needed, and how much of your enamel you are prepared to lose.

Bonding, in one paragraph

Resin shaped freehand onto the tooth in a single visit, usually with no drilling. Reversible in practice, repairable, and considerably less expensive. It stains over time and needs polishing at hygiene visits, and it will not brighten a genuinely dark tooth.

Veneers, in one paragraph

Thin porcelain made in a laboratory and bonded to a lightly prepared tooth. It holds colour and lustre for far longer, can mask darker shades, and handles larger changes in shape. But the preparation is permanent: once enamel is removed the tooth is committed to being restored for the rest of your life.

How I decide

• If the teeth are well positioned and the change is small — bonding
• If alignment is the real issue — aligners first, then reassess; often very little else is needed
• If the teeth are already heavily filled or broken down — porcelain, because there is little enamel left to protect
• If someone is under thirty with healthy enamel — almost always bonding, and a conversation about waiting
• If the wish is a dramatic colour change on dark teeth — whitening first, porcelain only if it falls short

The question worth asking

Ask any dentist proposing veneers how much enamel will be removed and what the plan is when they need replacing in fifteen years. A considered answer tells you more about the clinician than any photograph.
