Conservative Dentistry: Smart, Minimal, and Built to Last

By a dentist who’s been doing this for 40+ years—and still believes less is more.

What “conservative” really means

Conservative dentistry means restoring teeth with the least intervention that reliably solves the problem and preserves natural structure. It’s common-sense care designed to keep your smile healthy and beautiful for as long as possible—while avoiding unnecessary procedures and costs.

There are limits. For example, very dark teeth that don’t respond to modern whitening may benefit from veneers. Veneers look great, but they involve additional dentistry and higher costs, so I reserve them for cases where simpler options won’t achieve the result.

Small repairs: tooth-colored bonding

Back teeth often decay or chip in the middle, while the sides (cusps) remain intact. When only a small portion is missing—especially when corners aren’t involved—composite bonding can be ideal.

• What it is: A durable, tooth-colored resin shaped chairside and light-cured.
• Where it works: Front or back teeth.
• Why it’s great: Matches your tooth, preserves healthy structure, and can last for years with proper care.

Bigger breaks: bonded ceramic onlays

When a significant amount of tooth is missing, my restoration of choice is a bonded onlay—a custom “puzzle piece” that replaces only what’s gone.

1. We capture a 3D scan of your tooth—no messy impressions.
2. The lab designs a precise onlay and mills it from bondable ceramic.
3. We bond the onlay to enamel/dentin with modern adhesives, which can help reinforce the remaining cusps.

This differs from older silver amalgam fillings, which do not bond to tooth structure and rely on mechanical retention. Because they don’t bond, cusps can be left unsupported and more prone to fracture over time.

Onlays vs. crowns: preservation first

Crowns have their place, but they usually require removing more tooth. Onlays are often a better first option because they:

• Preserve more healthy tooth structure.
• Often avoid the need for a root canal and always avoid a post/core.
• Keep more future options open if new treatment is needed later.

I’ve restored broken teeth with onlays for decades. Years ago, many were gold; I still see patients with 40-year-old gold onlays that function beautifully. For roughly the last 20 years, bondable ceramics have been my go-to because they’re strong and highly esthetic. My long-term results have been excellent.

Why bite balance matters

Every restoration’s longevity depends on the forces placed on it. I often fine-tune the bite with selective bite adjustment and, when helpful, recommend tooth movement (orthodontics) to put teeth in a healthier, more stable position. The bonus: better function and a more attractive smile.

A quick story from the chair

A young adult came in with a small chip at the corner of a front tooth. A previous dentist had said such chips couldn’t be fixed predictably with bonding and suggested removing the tooth for an implant. That recommendation isn’t aligned with current conservative protocols.

In skilled hands, composite bonding can restore this kind of chip beautifully and predictably—and often last for many years when the bite is well balanced and home care is solid.

The bottom line

A great, healthy smile can last a lifetime. When we combine conservative procedures with a well-balanced bite, teeth—and the dentistry on them—tend to last longer. Better tooth position also improves cleanability, which supports gum health and decay prevention.

Better choices lead to better outcomes—and often save money. In the end, it’s your choice.

Quick glossary

• Onlay: A lab-made restoration bonded to your tooth that replaces missing parts while preserving healthy structure.
• Post/core: A support placed into a root-canal-treated tooth to help hold a crown when little tooth remains; conservative options often avoid this.
• Selective bite adjustment: Minor reshaping of enamel to reduce high spots and distribute chewing forces more evenly.

FAQ

Will whitening always work?
Not always. Some darker teeth don’t respond well. In those cases, veneers may be the most predictable esthetic solution.

NHow long do bonded onlays last?
With good case selection, a stable bite, and consistent home care, they can last many years. Gold and modern ceramics both have excellent track records.

When is a crown still necessary?
Front teeth that are badly broken down can benefit from a crown to improve both the aesthetics and strength. I find that back teeth rarely need crowns for restoration.

Considering treatment?

Ask your dentist:

• “Can we restore this conservatively?”
• “Would bonding or a bonded onlay preserve more tooth than a crown in my case?”
• “How will you make sure my bite doesn’t overload the restoration?”
