When a cavity gets too big or a tooth breaks, your dentist has several ways to fix it. The good news is that modern dentistry offers lots of choices, and each one works differently depending on how damaged your tooth is. Let's walk through what these options are and help you understand which one might be right for you.

Quick Fixes: Direct Fillings

The fastest option is a direct filling, which your dentist can complete in a single visit. Your dentist removes the decayed part of your tooth and fills it right away with a tooth-colored composite material. Think of it like sculpting the tooth back to its original shape during one appointment.

Direct fillings work great when less than 40% of your tooth is damaged. They cost between $150 and $300 and typically last 7-10 years with good care. The best part? Your natural tooth stays as much intact as possible, and you don't need to come back for multiple visits. However, these fillings need proper technique during placement, including careful dry conditions and proper etching (a special chemical that helps the filling stick).

Longer-Lasting Options: Inlays, Onlays, and Crowns

When your tooth has more damage, your dentist might recommend an indirect restoration. This means the restoration is made in a dental lab before being bonded to your tooth. It's like getting a custom-made piece rather than a quick fix.

Inlays fill cavities that involve more of the tooth's interior but don't cover the top. They typically run $650-$1,500 and last 10-20 years or longer. They work well when you've had a root canal or when one part of the tooth needs serious rebuilding. Onlays cover one or more of the tooth's bumpy parts (called cusps) while leaving some healthy tooth showing. They cost $750-$1,600 and last 10-20 years. Onlays are perfect when your cavity is bigger than an inlay can handle, but your tooth isn't so damaged that it needs a full crown. Crowns are like a custom cap that covers your entire tooth. They're used when more than 50% of your tooth is damaged, after root canal treatment, or when you need major cosmetic changes. Crowns range from $1,000-$3,000 depending on material, and they typically last 15-25 years with proper care.

Choosing Your Material

The material your restoration is made from matters a lot for how long it lasts and how it looks.

Composite Resins are tooth-colored materials that look natural. They're reversible and require less tooth removal than other options, making them great for conserving your natural tooth structure. The downside is they don't last quite as long in very high-stress areas of your mouth. Ceramic (Porcelain) restorations look incredibly natural and are very durable. Traditional porcelain lasts about 10 years, while newer formulas like lithium disilicate can last 15+ years with excellent durability. Gold Restorations are the gold standard for longevity—literally! Gold restorations can last 30+ years because of how well they adapt to tooth surfaces and how resistant they are to damage. The only downside is cost ($1,200-$2,500) and appearance, so they're typically used on back teeth you don't see when you smile. Zirconia is an ultra-strong ceramic material that's especially good for back teeth in people with heavy bites. It lasts about 10+ years and resists damage beautifully, though it was originally more opaque than natural tooth color (though newer versions look more natural).

Same-Day Restorations: Technology Making Dentistry Faster

Some dental offices now use special computer technology to design and create restorations right in the office while you wait. No temporary restoration, no second visit—you leave with your permanent restoration in place. These same-day restorations work just as well as lab-made ones and last 5+ years.

What's Right for Your Tooth?

Your dentist will consider several things when deciding which restoration fits best:

If your cavity is small (less than 40% of the tooth), a direct filling is usually the fastest, most economical choice. If your cavity is moderate (40-50% of the tooth or involves multiple bumps), an inlay or onlay gives you durability and a longer lifespan than a filling. If your cavity is large (over 50% of the tooth), a crown provides the best protection and predictable long-term results. If you grind your teeth at night, your dentist will probably recommend stronger materials and might suggest a night guard to protect your restoration.

Making Your Restoration Last

No matter which restoration you choose, you can help it last as long as possible by:

  • Brushing twice daily and flossing daily
  • Avoiding hard foods or using your teeth as tools
  • Wearing a night guard if you grind your teeth
  • Visiting your dentist every 6 months
  • Addressing any sensitivity or discomfort promptly
Your dentist will explain the pros and cons of each option during your consultation, and together you can choose the restoration that fits your mouth, your budget, and your lifestyle.
