Do I Need Healthy Teeth
and Gums for Veneers?
Yes, and here is why.

Why gum health is non-negotiable

Active gum infection changes the landscape of your mouth continuously. Inflamed gum tissue bleeds, swells, and recedes in ways that shift daily, making it impossible to take accurate impressions for veneer fabrication or to seat the veneers at the correct margin depth. The margin, where the veneer edge meets the gum, is a critical seal. Get it wrong and bacteria re-enter, the veneer edge shows, and sensitivity develops.

Many patients are unaware they have gum disease. Bleeding when brushing is often normalised as a sign of brushing too hard rather than recognised as infection. At Picasso Dental we perform periodontal probing at every veneer consultation: a thin probe inserted gently around each tooth measures pocket depth and identifies diseased sites. A reading above 3mm with bleeding signals disease that must be treated before any cosmetic work.

Treatment depends on severity. Early-stage disease responds to professional scaling in one or two visits followed by improved home care. Moderate disease requires scaling and root planing under local anaesthetic, then four to six weeks of healing before we reassess. Only once gum measurements are stable do we proceed with veneers.

Tooth structure: what veneers actually bond to

Porcelain veneers bond to enamel. The adhesive system used in veneer placement is designed for a strong, lasting bond to the crystalline structure of healthy enamel. When decay is present, the bond attaches to compromised, softened dentine instead: a weaker substrate that flexes differently and does not hold the adhesive with the same long-term reliability.

Small cavities are filled before preparation, often in the same appointment if they are minor. Old, failing fillings are replaced with fresh composite to create a sound substrate for the veneer bond. Teeth with large existing restorations, fractures, or extensive decay are assessed individually. Some are better candidates for crowns, which cover the entire tooth and provide full structural reinforcement where a veneer's partial coverage would not be adequate.

Bite and grinding: the mechanical threat

Veneers cover the front surfaces of teeth. They are not designed to absorb heavy lateral forces from a grinding habit or to compensate for a bite where opposing teeth strike them at a steep angle. Both situations create concentrated stress that leads to chips and fractures.

We assess every patient's bite using articulating paper and clinical examination. Patients who grind need a custom nightguard, fabricated after veneers are placed, to protect the porcelain during sleep. Patients with bite problems may benefit from equilibration: a careful adjustment of the bite so that forces are distributed evenly before veneers are placed.

"Making the decision to go to Hanoi and have the dental treatment done by Picasso was one of the best decisions I have taken for a long time."

Root canal treated teeth and veneers

Teeth that have had root canal treatment are structurally more brittle because the pulp, which supplied moisture and nutrients to the dentine, has been removed. This increases fracture risk under stress. We assess each root-treated tooth individually. Heavily restored or significantly discoloured root-treated teeth often do better with crowns, which encase the entire tooth and provide reinforcement along the full circumference. Where the tooth structure is largely intact, conservative veneers can be placed with enhanced bonding protocols.

What the evaluation process looks like at Picasso Dental

At every veneer consultation we take full-mouth digital X-rays, perform periodontal probing, assess bite mechanics, and take photos and impressions if needed for planning. Some patients leave the first appointment with a confirmed start date for veneer preparation. Others leave with a short treatment plan addressing gum disease or decay before we can proceed.

The distinction between these two groups does not reflect on the patient. It reflects the reality that a lasting result requires an honest baseline assessment. Veneers placed on healthy teeth and healthy gums consistently perform well for ten to fifteen years or longer. Veneers placed prematurely over untreated problems rarely reach five years before requiring replacement at full cost.
