Who Should Not Get Veneers?
Most people who are told "not veneers" are really being told "not yet" or "something smaller first." Here is what rules veneers out, what the research says about each reason, and what to do instead.
Veneers are a poor choice when gum disease, decay or grinding hasn't been treated, when there is too little enamel left to bond to, or when whitening, bonding or aligners would fix the problem with less tooth removed. Grinders had about 7.7 times the risk of veneer failure in a 20-year study,1 and veneers on enamel had about 99 percent survival versus about 91 percent on exposed dentin.2 Most of these reasons can be fixed first.
What disqualifies you for veneers
The common deal-breakers are untreated gum disease or decay, untreated grinding, too little healthy enamel, and teeth that a smaller treatment would fix just as well.
Very few people are ruled out for good. Most of the reasons below mean "not yet" or "something else first." The table shows what each problem does to a veneer and what usually comes before it.
| Reason | What it does to a veneer | What usually happens first |
|---|---|---|
| Gum disease or active decay | Veneers are bonded at the gumline. Inflamed or bleeding gums make a clean bond hard and leave dark, swollen edges. Decay under a veneer keeps going. | Cleanings, gum treatment and fillings. Veneers come after the mouth is healthy. |
| Grinding or clenching that isn't managed | Grinders had about 7.7 times the risk of veneer failure in a 20-year study.1 | A night guard, and sometimes bite work. See tooth grinding. |
| Little enamel left, or a lot of old filling | Veneers bonded to enamel had about 99 percent survival; with a lot of dentin exposed it was about 91 percent. Over old composite, only about 70 percent went without a repair.2 | Sometimes bonding or a crown is the better choice for that tooth. |
| Crowded or tipped teeth | Lining up crooked teeth with veneers alone means cutting deep into some of them, which pushes the bond into dentin. | Clear aligners first, then smaller veneers or none at all. See clear aligners. |
| A dark tooth that had a root canal | Veneers on teeth without a living nerve failed significantly more often in a 20-year study.1 | Often internal bleaching, then a veneer or crown planned for that tooth. See whitening. |
| Teeth that only need to be whiter | Veneers lock in one color. Healthy teeth that only need brightening lose enamel for no reason. | Whitening, and bonding for small chips. |
Smoking is not a deal-breaker, but smokers had more staining along veneer edges in the same 20-year study.1
Why some dentists advise against veneers
Most dentists who say no are worried about removing healthy enamel for a result that will need upkeep for life.
That worry is fair. It rests on four facts that patients rarely hear from ads.
- Prepared enamel does not grow back3 to 30%
In a lab study, veneer preparations removed about 3 to 30 percent of the crown of the tooth by weight. That is far less than a crown, but it is permanent.3 See how much tooth is removed.
- Veneers are a lifetime commitment53%
In routine UK health service practice, about 53 percent of porcelain veneers went 10 years without any further treatment on that tooth4. A veneer is not a one-time purchase.
- Most problems show up earlyEarly years
Fracture was the most common veneer problem and debonding the next most common, and both happened mostly in the first years after the veneers were bonded5.
- Deep preps do worse99% vs 91%
Survival for veneers on enamel compared with veneers on a lot of exposed dentin.2 Aggressive shaving to make teeth look straighter or brighter costs the tooth and the veneer.
There is a fifth reason dentists push back: the "veneers" in many social media videos are really full crowns on healthy teeth, with every side of the tooth cut down. Seeing those results, many dentists say no to anything that looks like a request for the same thing. The difference is explained in what happens to teeth under veneers.
Disqualified, or just "not yet"?
Gum disease, decay, grinding and crowding are usually fixable, so a no today can become a yes in a few months.
When a dentist turns you down, ask which kind of no it is. Here is how it usually breaks down:
- "Not yet": gum inflammation, cavities, an unmanaged grinding habit, crowding that aligners can fix, a dark tooth that may bleach.
- "Something smaller would do": one chip, a small gap, mild staining, short or slightly worn edges. Bonding or whitening often wins here. See veneers vs bonding.
- "Something bigger is needed": broken teeth, very large fillings, or teeth that have lost much of their structure. A crown protects the tooth better. See materials compared.
- "Probably never a good idea": severe grinding that a person won't treat, or a goal that requires cutting healthy teeth down to stubs.
Is it bad to put veneers on healthy teeth?
It depends on how much tooth is removed: thin, enamel-bonded veneers on healthy teeth do very well, while heavy preparation of healthy teeth is the real harm.
Healthy teeth with good enamel are actually the best foundation for a veneer, because the bond to enamel is the strongest.2 The problem is not the healthy tooth. It is a plan that grinds it down to change its position or to hide a very dark color, when other steps would get there with less cutting.
Some teeth need no shaving at all, such as small, worn or gapped teeth that the veneer makes slightly larger. That is why a mock-up of the planned shape, tried on your own teeth first, is so useful: it shows how much room the veneer needs before anything is touched.
Better options for common problems
For many single problems, a smaller treatment beats veneers.
| Your concern | Often better than veneers |
|---|---|
| Yellow or stained teeth that are otherwise fine | Whitening |
| One chip, a small gap, a dark triangle | Bonding, including the Bioclear method |
| Crooked or crowded teeth | Clear aligners, then decide |
| A broken or heavily filled tooth | A crown |
| Several teeth with the wrong shape, size or color | This is where veneers shine. See dental veneers. |
Questions to ask if you're told no
Ask what the reason is, whether it can be fixed, and what the alternative would cost the tooth.
- Is the reason my gums, decay, my bite, my enamel, or the goal itself?
- Can it be treated first, and how long would that take?
- What would you do instead, and how much tooth would that remove?
- Would straightening or whitening first reduce how many veneers I need?
- If I grind, what protects the veneers afterward?
A second opinion is reasonable either way. A good answer explains the trade-off; it doesn't just say yes or no.

Dental veneersQuestions about who can get veneers
What disqualifies you for veneers?
Untreated gum disease or decay, grinding that isn't managed, too little healthy enamel, and teeth that whitening, bonding or aligners would fix with less tooth removed. Most of these are "not yet" rather than "never": treat the gums, fill the cavities, protect against grinding, and veneers often become a good option.
Why do dentists advise against veneers?
Mainly because prepared enamel doesn't grow back and veneers need upkeep for life. In routine UK practice, about 53 percent of veneered teeth went 10 years with no further treatment.4 Deep preparation also hurts results: survival fell from about 99 percent on enamel to about 91 percent on exposed dentin.2
Can you get veneers if you have gum disease?
Not until it is treated. Veneers are bonded right at the gumline, and inflamed gums bleed, make bonding unreliable and leave dark or puffy edges. Once the gums are healthy and stable, veneers can be planned.
Can you get veneers if you have cavities?
The cavities are treated first. Small ones may be filled as part of the veneer preparation, but large fillings change the plan, because veneers bonded over old composite needed repairs more often.2
Can you get veneers if you grind your teeth?
Often yes, but only with the grinding managed. Grinders had about 7.7 times the risk of veneer failure in a 20-year study.1 A night guard worn every night is the usual protection. See tooth grinding.
Can you get a veneer on a tooth that had a root canal?
Sometimes. Veneers on teeth without a living nerve failed more often in a 20-year study,1 and dark root-canal teeth are hard to cover with a thin veneer. Internal bleaching first, or a crown, is often the better plan.
Can you get veneers if you smoke?
Yes, but expect more staining at the edges. Smokers had significantly more edge staining in a 20-year veneer study.1 It is a looks problem, not a failure of the veneer.
Is it bad to get veneers on healthy teeth?
Not when the preparation is small and stays in enamel, which is where veneers last best.2 The harm comes from cutting healthy teeth down heavily to change their position or hide a dark color. A mock-up shows how much room a veneer really needs.
Can veneers fix crooked teeth?
Mildly crooked teeth, sometimes. Badly crowded teeth usually need too much cutting, so straightening with clear aligners first often means smaller veneers or none at all. See clear aligners.
What should I do if a dentist says I'm not a candidate?
Ask which reason applies and whether it can be treated first. A second opinion is reasonable. A good answer explains the trade-off and what the alternative would cost the tooth.
