If you are thinking about a dental crown, you need to know when a tooth cannot be saved with a crown. This guide explains when a crown works, when it does not, and what your next step should be. You will learn how a dentist decides if you can still get a crown or if the tooth needs a different dental treatment.
When does a tooth need a crown?
A dental crown is a tooth-shaped cap placed over a damaged tooth to restore its strength and appearance. Your dentist will recommend a crown when the tooth structure is weak, cracked, or heavily filled.
A broken or cracked tooth, chipped tooth, or severe decay often means the tooth needs a crown. A crown can save the tooth by covering the underlying tooth and helping protect the tooth from further damage.
In many cases, a crown is used after a root canal treatment when the dental pulp has been removed, and the tooth is sealed.
When is there not enough tooth structure for a crown?
A crown needs support from the remaining tooth. If there is not enough tooth remaining, the dentist cannot safely attach the crown.
Severe tooth decay or trauma can reduce the amount of tooth material. If there is not enough tooth remaining above the gum line, a crown may not stay secure.
In this situation, your dentist may suggest building up the tooth first or moving to another option, such as a dental implant.
Can a tooth with severe decay still get a crown?
If decay has reached deep into the tooth, the dentist must remove all decay before placing a crown. If too much structure is lost, the tooth may not be saved with a crown.
A root canal to remove infected pulp may help. This allows the natural root to stay in place while the crown restoration rebuilds the visible tooth.
If the risk of the tooth failing is too high, the tooth may need to be extracted.
What if the tooth is cracked or broken?
If your tooth is cracked but stable, a crown may be the best option. Your dentist secures the crown with dental cement to hold the tooth together.
If a crack extends below the gum or into the root, the tooth cannot be repaired. Your dentist will remove it and may suggest a replacement.
Your dentist will evaluate the tooth to decide whether it can be restored or not.
Is a crown necessary after a root canal?
After root canal treatment, the tooth becomes more fragile. A crown protects the tooth and restores its strength after a root canal.
Front teeth may not always need a crown, but back teeth typically do because they take on more pressure when you chew.
If you are unsure whether a crown is necessary after a root canal, speak to a dental professional for advice.
Can gum problems stop you from getting a crown?
Healthy gum support is essential. If gum disease affects the stability of the tooth, placing a crown may not work.
The dentist may first treat the gum condition as part of your dental care. Once your oral health improves, you may still get a crown.
If the tooth does not have enough support, extraction may be the safer option.
What happens if you go without a crown?
If your dentist says you need a crown and you go without a crown, the tooth may weaken further.
A tooth that has undergone a root canal without protection can fracture. This increases the chance that the tooth will need to be extracted later.
Early crown placement can reduce long-term cost and protect your surrounding teeth.
Are there alternatives if a crown is not possible?
If a crown cannot be placed, other treatments are available. A dental implant can replace a missing tooth and restore function.
In some cases, dental veneers may work for front teeth if the damage is minor. Veneers do not offer the same level of strength as a crown.
Your dentist will explain whether a crown or another solution is best for your needs.
What does the crown procedure involve?
The dentist prepares the tooth by trimming it slightly to make space for the crown. A temporary crown protects the tooth while your new crown is made.
At your next visit, the crown is fitted, and it is attached securely. The crown in place restores shape and function.
