Dental crowns and veneers can last for a decade or longer, but only if you treat them differently than you treat the rest of your smile. These restorations are strong, but they still depend on the health of the tooth structure and gum tissue underneath and around them, and a few daily habits make the difference between a crown that lasts five years and one that lasts fifteen.
At Newport Beach Dental Center, Dr. Laura Sharbash, DDS, FAGD, D.ABDSM, places dental crowns and veneers and guides every patient on how to protect that investment afterward. The tips below cover the daily habits, the foods and behaviors to avoid, and the professional maintenance schedule that keeps your restorations looking natural and functioning well for as long as possible.
Understanding Your Dental Restorations
Before getting into maintenance, it helps to know what you are actually caring for. Dental crowns are cap-like restorations that cover an entire damaged tooth, restoring both its strength and its shape. Modern crowns are typically made from porcelain, ceramic, porcelain-fused-to-metal, or gold, and each material behaves a little differently over time. Veneers are thin shells bonded to the front surface of a tooth to improve its appearance. They are usually made from porcelain or composite resin and are used primarily for cosmetic enhancement rather than structural repair. If you are still weighing your options, our comparison of dental bonding and veneers explains how the two differ.
Both restorations are durable by design, but neither is indestructible. The porcelain or composite itself resists staining and wear reasonably well, though the margin where the restoration meets your natural tooth, and the natural tooth structure underneath, remain just as vulnerable to plaque and decay as any other part of your mouth.
How Long Do Crowns and Veneers Actually Last?
This is one of the most common questions we hear, and the honest answer is that it depends on the material, your bite, and how consistently you maintain them. Porcelain veneers typically last 10 to 15 years, and well-maintained cases can continue performing well past the 15 to 20 year mark. Composite resin veneers are less durable and more prone to staining, generally lasting 5 to 7 years before they need replacement or refinishing.
Crowns tend to hold up well too. A five-year study of single-unit crowns published in Dentistry Journal in 2021, which followed porcelain-fused-to-metal and metal crowns placed in a university teaching clinic, found an overall cumulative survival rate of 83.9 percent at the five-year mark, with metal crowns performing slightly better than porcelain-fused-to-metal crowns from year four onward. In practice, many crowns continue functioning well beyond five years when the surrounding tooth and gum tissue stay healthy and the patient keeps up with routine care.
These numbers are averages, not guarantees, and your own restoration may last longer or shorter depending on grinding habits, diet, and how quickly small issues get addressed.
Daily Care Habits That Protect Your Restorations
Maintaining your dental restorations starts with the same daily habits that protect the rest of your smile, applied a little more carefully. Brush twice daily with a soft-bristled toothbrush, since hard bristles or aggressive brushing can scratch porcelain surfaces and irritate the gum line around a restoration. Floss daily around every restoration, paying particular attention to the margin where the crown or veneer meets your natural tooth, since plaque tends to collect there. Choose a non-abrasive toothpaste and avoid whitening formulas or those containing baking soda, which can be too abrasive for porcelain over time. Many patients also benefit from an antimicrobial mouth rinse, which can help reduce plaque buildup around the restoration margins between brushings.
It is worth remembering that while the restoration material itself cannot decay, the natural tooth structure underneath or adjacent to it can still develop a cavity, so these habits protect more than just the crown or veneer.
Protecting Your Restorations From Damage
Beyond basic hygiene, a few protective habits go a long way toward extending the life of your dental work. If you grind your teeth at night, a nightguard is one of the most effective ways to prevent the chipping, cracking, and premature wear that bruxism causes, since grinding places repeated stress on both the restoration and the bond that holds it in place. If you play sports, wearing a sports mouthguard protects your restorations from any impact to the face. Try not to use your teeth as tools for opening packages, cutting thread, or biting your nails, and be cautious with very hard foods like ice, hard candy, and nuts, all of which can chip or dislodge a restoration if bitten directly.
Foods and Habits to Avoid
Certain foods and habits pose particular risks to crowns and veneers. Sticky foods such as caramels and taffy can potentially pull at the margins of a restoration or dislodge it altogether. Dark-colored beverages like coffee, tea, and red wine will not stain porcelain the way they stain natural enamel, but they can gradually discolor the margins and any composite bonding material over time. Tobacco products stain restorations and compromise the health of the surrounding gum tissue, and heavy alcohol consumption can weaken bonding materials through dehydration. If you enjoy staining beverages regularly, drinking them through a straw can help minimize contact with your front teeth.
If you plan to whiten your natural teeth, the timing matters. Porcelain and composite do not respond to whitening, so professional options such as Zoom teeth whitening are usually best done before new front restorations are shade-matched, not after.
Regular Professional Maintenance
Your at-home routine works best alongside consistent professional care. Attending your six-month checkups and cleanings allows us to identify and address any issues with your restorations before they become serious problems, and professional polishing with agents designed for dental restorations helps maintain their natural luster. During these visits, we evaluate your restorations for wear, check the margins where they meet your natural tooth, and confirm the surrounding gum tissue remains healthy. Our post on the importance of regular dental checkups explains what else those visits catch.
A few situations call for contacting our office sooner than your next scheduled visit. Reach out to us if any of the following happens:
- A crown or veneer feels loose or shifts when you bite down
- You notice pain or sensitivity around a restoration
- You see a chip or crack in the restoration itself
- Your bite feels different than it did before
- The restoration’s color changes noticeably compared to the surrounding teeth
Addressing these issues early can often prevent a more extensive, and more costly, repair down the line.
Why Biomimetic Dentistry Supports Longer-Lasting Results
Dr. Sharbash’s approach to restorations follows biomimetic dentistry principles, meaning treatments are designed to mimic the natural strength and flexibility of your original tooth structure rather than simply covering it. You can read more about the philosophy behind this conservative approach and why it tends to create a stronger, more seamless bond between a restoration and the tooth beneath it. In practice, this conservative preparation preserves more of your natural tooth structure up front, which can support a longer-lasting result when paired with the daily and professional care outlined above.
Dr. Laura Sharbash, DDS, FAGD, D.ABDSM, is a Fellow of the Academy of General Dentistry and a Diplomate of the American Board of Dental Sleep Medicine, and she brings that same conservative, detail-oriented approach to every restoration she places. Your crowns and veneers represent a real investment in both your oral health and your confidence, and with the right care, they can continue looking natural and functioning well for many years.

Frequently Asked Questions About Caring for Crowns and Veneers
How long do dental veneers last?
Porcelain veneers typically last 10 to 15 years, and many well-maintained cases continue performing well past 15 to 20 years. Composite resin veneers are less durable and generally last 5 to 7 years before they need replacement or refinishing. Consistent oral hygiene and avoiding habits like nail biting or chewing ice can help your veneers reach the longer end of that range.
Can you whiten a dental crown or veneer?
No, whitening treatments and whitening toothpaste do not change the shade of porcelain or composite restorations the way they change natural enamel. If a crown or veneer no longer matches the rest of your smile after whitening your natural teeth, the restoration may need to be replaced to restore a consistent shade across your smile.
What happens if a veneer or crown chips?
A small chip does not always mean the entire restoration needs to be replaced. Depending on the size and location of the chip, we may be able to smooth or repair it during an office visit. Larger chips or cracks that expose the underlying tooth typically call for a full replacement, so it is worth having any chip evaluated promptly rather than waiting.
Do crowns and veneers get cavities?
The restoration material itself cannot decay, but the natural tooth structure underneath a crown or adjacent to a veneer can still develop a cavity if plaque builds up along the margins. This is why daily flossing around restorations and regular checkups remain important even after a tooth has been restored.
Is a nightguard really necessary if I have crowns or veneers?
If you grind or clench your teeth at night, a nightguard can meaningfully lower the risk of chipping, cracking, or debonding a restoration. Grinding places repeated pressure on crowns and veneers that they are not designed to absorb over the long term, so a properly fitted nightguard is one of the most effective ways to protect the investment you have already made.
