There is a moment a lot of patients recognize. You bite down on something and one specific tooth objects. It might not hurt constantly, but it lets you know when pressure lands the wrong way.
That tooth is usually telling you a filling will not solve the problem anymore. Crowns and bridges are what we use when a tooth needs structural help rather than a patch, and understanding the difference makes the recommendation far less mysterious.
The difference between crowns and bridges
A crown covers a tooth that is still in your mouth but structurally compromised. It wraps the whole visible portion and holds it together, like a helmet.
A bridge replaces a tooth that is gone. It uses the teeth on either side of the gap as support and carries a replacement tooth between them, cemented in place so it does not come out.
Both are custom made to fit your bite and matched to your surrounding teeth.
When crowns are the right call
We recommend a crown when the remaining tooth cannot be trusted to survive normal chewing on its own. Typical situations:
- A cracked tooth, or one with a fracture line running down a cusp.
- A cavity so large that the walls of the tooth are thin and flexing.
- A tooth that has had root canal treatment, which becomes more brittle afterward.
- An old filling that has been repaired repeatedly until there is more filling than tooth left.
- Significant wear from grinding that has flattened and weakened the tooth.
- A cosmetic case where a back tooth is discolored or misshapen enough to bother you.
Cracks are the one people underestimate. A crack does not heal, and every bite works it slightly wider. Crowned early, the tooth is usually saved. Left long enough, the crack can travel below the gumline, and at that point extraction becomes the only option. That is the single most common preventable loss we see.
When dental bridges make sense
If a tooth is already missing, a bridge is one of several ways to fill the space. It tends to be the right answer when the neighboring teeth would benefit from crowns anyway, when you want a fixed solution rather than something removable, or when bone volume or health history makes an implant less practical.
Filling the gap is not only cosmetic. Teeth rely on their neighbors for position. Leave a space and the adjacent teeth start to tip toward it while the opposing tooth drifts down into the opening. Your bite changes, cleaning gets harder, and years later fixing everything becomes a much bigger project than replacing one tooth would have been.
Implants and partial dentures are the other options, and we will lay out all of them with their trade-offs rather than steering you to one.
What getting crowns and bridges involves
For a crown, we shape the tooth to make room for the crown to sit over it, take digital records of the prepared tooth and your bite, and fit a temporary crown while the permanent one is made. At the second visit we try in the permanent crown, check the fit and the bite carefully, adjust as needed and cement it.
A bridge follows the same pattern, with the supporting teeth prepared at the same appointment.
Both are done under local anesthetic, and nitrous oxide is available if you would rather not be fully present for it. Most patients report the temporary phase is the least comfortable part, and it is short.
The bite check deserves emphasis. A crown that is high by a fraction of a millimeter feels wrong every time you close your mouth and can leave a tooth sore for weeks. We spend the time on that adjustment before you leave.
Living with crowns and bridges day to day
Both need the same care as natural teeth, plus a little extra attention at the margins.
Brush and floss normally, and pay attention to the gumline where the crown meets the tooth, because that junction is where new decay starts. A bridge needs cleaning underneath the replacement tooth, and we will show you the tool that makes that easy; skipping it is the usual reason a bridge fails early.
Avoid using them on ice, popcorn kernels and hard candy. If you grind at night, a guard protects your investment. Come to your regular checkups so we can watch the margins and the supporting teeth over time.
How long crowns and bridges last
A well-made crown on a healthy foundation commonly lasts many years. What ends its life is almost never the crown material. It is decay at the margin or gum problems around the supporting tooth.
That is the useful takeaway: the crown does not get cavities, but the tooth underneath it still can. Good hygiene and regular visits are what turn a crown into a long-term solution instead of a temporary one.
Get crowns and bridges in Berkeley before a tooth breaks
The most expensive dentistry is the kind that happens after waiting. A tooth that needed a crown in March and gets attention in December may need root canal treatment first, or may not be savable at all.
If you have a tooth that twinges under pressure, feels sensitive to cold in one specific spot, or has an old filling that keeps chipping, get it looked at while the answer is still simple. We accept most dental insurance plans and all major credit cards, and there is an in-office membership plan for patients without coverage, so cost can be planned rather than guessed at.
