Dra. Cléo Salustiano Composite veneers: what they are, who they suit and how treatment works
Updated 7 Nov 2026
Short answer
Composite veneers are thin layers of composite resin applied and sculpted directly onto the front of the teeth, in the dental chair, to adjust colour, shape, size, worn edges and small gaps. They usually need little or no reduction of the tooth and are generally done in one long session per arch. Thin composite veneers (known in Brazil as "lentes de resina") are the thinnest version. Treatment needs periodic maintenance with polishing, and whether it is indicated depends on an assessment of the teeth, gums and bite.

Book an assessment on WhatsAppWhat composite veneers are
A composite veneer (also called a direct veneer or composite bonding veneer) is a layer of composite resin, the same type of material used in tooth-coloured fillings, applied in layers over the visible surface of the tooth. The dentist shapes the resin on the spot, tooth by tooth, adjusts proportion, length and outline, and finishes with polishing.
Because it is built directly in the mouth, the technique needs no lab stage and allows adjustments and repairs in the office. On the other hand, resin can lose shine and pick up stains over time, so maintenance is part of the treatment.
Composite veneers vs thin composite veneers
A thin composite veneer is a thinner veneer, used for subtler changes, and usually needs minimal or no reduction. A veneer can be slightly thicker when there is more colour or shape to correct. Both names describe the same family of treatment, and which one fits your case is decided at the assessment. See veneer or "dental contact lens"? and layered thin composite veneers.
Who composite veneers usually suit
- Stained teeth that do not respond well to whitening (whitening or veneers?).
- Small gaps between teeth (bonding, veneer or braces?).
- Worn, chipped or uneven edges.
- Teeth whose shape or size is out of balance with the smile.
- Mild misalignment that can be masked by adding material (can veneers fix crooked teeth?).
- Replacing old veneers or fillings that have lost colour or shape (redoing old veneers).
In every case, the indication depends on the exam: gum health, bite, habits and what you expect from treatment.
When they are not indicated or need to wait
- Active decay or a leaking filling: treated first, because resin on an unhealthy base does not hold.
- Inflamed or bleeding gums: gum health comes before aesthetics (why the gums come first).
- A tooth sticking out, several teeth set back or an unfavourable bite: veneers do not correct the bite, and the path may start with braces or aligners.
- Uncontrolled bruxism: it does not rule treatment out, but it changes the plan and usually calls for a night guard from the start (bruxism and veneers).
- A tooth darkened from the inside, such as some root-canal-treated teeth: it may need internal whitening or another approach first (veneers on a root-canal tooth).
- Expecting a standard result: every smile responds differently, and the plan starts from your case.
How it is done, step by step
This is how treatment usually goes at Dr. Cléo Salustiano's office:
- Photo pre-assessment (optional)You send photos of your smile on WhatsApp, from the front and both sides, and receive initial guidance. It does not replace the exam.
- Assessment appointmentAn exam of the teeth, gums and bite, deciding how many teeth are included, the shade and the steps. It takes about 30 minutes.
- Treatment planPresented before you decide, including anything that needs to be done before the resin, such as treating the gums or whitening.
- ApplicationThe resin is placed in layers, sculpted and polished in the same session, usually one arch at a time. Local anaesthetic is used when needed.
- Follow-up and maintenanceA follow-up visit for adjustments and periodic maintenance, about every four months, for polishing and checking the edges.

How long composite veneers last
There is no fixed lifespan. The articles on our blog work with an average of five to eight years, which can be longer or shorter depending on the resin, the technique, the bite and, above all, daily care. Some loss of shine and wear over time are features of the material and are usually handled with polishing or a spot repair.
| Factor | Effect on lifespan |
|---|---|
| Bruxism (grinding or clenching) | One of the factors that most shorten the life of any cosmetic work |
| Using teeth as tools, nail biting | Leads to chips and fractures |
| Poor hygiene | Plaque builds up at the edges, where problems start |
| Coffee, tea, red wine, dark soft drinks and smoking | Speed up loss of colour and shine |
| Abrasive toothpaste | Wears down the resin polish |
| Night guard, when indicated | Protects the veneers and the teeth themselves |
| Regular check-ups with polishing | Refresh the appearance and allow spot repairs |

Everyday care
- Brush with a low-abrasion toothpaste and floss every day.
- Watch coffee, tea, red wine, dark soft drinks and smoking.
- Do not use your teeth to open packages and avoid nail biting.
- Wear a night guard when one is indicated for bruxism.
- Periodic maintenance, about every four months, with polishing and a check of the edges and gums (what maintenance involves).
- If a veneer chips, breaks or comes loose: keep the fragment, do not glue it at home and book an assessment (broken veneer: what to do).

Composite vs porcelain
Both cover the tooth to adjust colour and shape, but the process is different. Neither material suits every case: the choice balances your goal, the structure of your teeth, your bite and the maintenance routine that makes sense for you.
| Composite | Porcelain | |
|---|---|---|
| How it is made | Applied and shaped in layers by the dentist, on the tooth | Made in a lab and then bonded |
| Tooth preparation | Usually more conservative: often minimal or no reduction | Usually needs slightly more preparation |
| Sessions | Usually fewer sessions | More steps, because of the lab stage |
| Stains and shine | Can pick up stains and lose shine over time | Tends to pick up fewer stains |
| Maintenance | Periodic polishing and more care with coffee, wine and smoking | Less demanding in this respect |
| Repair | Simpler to repair in the office | More complex repair if it fractures |
| Bruxism | Calls for a night guard | Calls for a night guard |

What affects the cost of composite veneers
This page does not list prices: Brazilian dental advertising rules do not allow it, and a figure given before an exam would have no basis. The cost is presented in the treatment plan, after the assessment. What changes from one plan to another:
- Number of teeth: it comes from your smile line and the risk of contrast with neighbouring teeth (how many teeth are included).
- Material and technique: direct composite, indirect composite or porcelain involve different sessions and steps.
- Condition of the base: decay, old fillings and inflamed gums are treated first and appear as separate steps.
- Earlier steps: whitening and alignment change what the veneer needs to solve.
- Case complexity: internal stains, root-canal teeth, gum contour and bruxism need more adjustment sessions (what makes a case complex).
- Planning and finishing: photos, bite exam, choice of colour and shape, and adjustment sessions.
- Maintenance: periodic polishing and, over the years, repair or replacement.

Frequently asked questions about composite veneers
Do composite veneers damage the teeth?
+
When properly indicated, they usually need little or no reduction and preserve the tooth structure. The amount of preparation varies from case to case and is explained before starting.
Do composite veneers hurt?
+
They are not usually painful. Preparation is minimal or none, and local anaesthetic is used when needed. The most common discomfort is keeping your mouth open during the session.
Do composite veneers stain?
+
They can lose shine and pick up stains over time. With good hygiene, care with coffee, wine and smoking, and polishing at maintenance visits, discoloration can be kept under control.
How long do composite veneers last?
+
There is no fixed lifespan. The articles on our blog work with an average of five to eight years, varying with the resin, technique, bite, habits and maintenance.
What is the difference between composite veneers and thin composite veneers?
+
A thin composite veneer is a thinner veneer for subtler changes and usually needs minimal or no reduction. A veneer can be slightly thicker when there is more to correct. The choice is made at the assessment.
Are composite veneers reversible?
+
When placed with little or no reduction, they tend to be more reversible than other techniques. Every case is different, and the amount of preparation is explained before starting.
Do I need whitening first?
+
There is no fixed rule. The shade is defined during planning. In some cases whitening first makes sense; in others it does not change the plan.
Can people who grind their teeth have composite veneers?
+
Bruxism does not rule them out, but it is part of the plan: a night guard is usually indicated from the start.
How many sessions do composite veneers take?
+
Usually an assessment of about 30 minutes and one long application session per arch, followed by a follow-up visit and periodic maintenance. The exact number depends on how many teeth are included and what needs to be done first.
How much do composite veneers cost?
+
The cost is presented in the treatment plan, after the assessment, because it depends on the number of teeth, the technique, what needs to be done first and maintenance. The factors are explained in the cost section of this guide.
