A dental crown is a custom cover that fits over a tooth. It restores the tooth’s shape and function and can protect tooth structure weakened by decay, a fracture, or a large filling. A crown can also be attached to an implant to replace a missing tooth; that is a different situation from covering a natural tooth.
When might a dentist recommend a crown?
Your dentist may discuss a crown if a tooth is broken, severely worn, weakened, or extensively filled. Crowns can also support a dental bridge or restore an implant. The right treatment depends on how much healthy tooth remains, the condition of the root and gums, your bite, and what you want the tooth to look like. A filling or another restoration may be appropriate when less tooth structure needs replacing. A crown does not make a tooth immune to decay or gum disease.
A cracked tooth needs an examination: some cracks can be managed with a crown, while others extend too far to save the tooth. Ask your dentist what the examination and any X-rays show before choosing treatment.
What are crowns made from?
Common options include ceramic or porcelain, metal, porcelain fused to metal, and resin. Some ceramics can be matched closely to the surrounding teeth. Metal may be considered where strength is important, especially on teeth less visible when you smile. Each choice has tradeoffs in appearance, durability, the amount of tooth preparation, and cost. Ask which material suits the particular tooth and your bite, especially if you grind your teeth or have a metal sensitivity.
What happens during the procedure?
- Assessment and preparation: The dentist examines the tooth and removes decay if present. The tooth is then shaped so the crown can fit. This generally means removing some enamel; a buildup may be needed when substantial tooth structure is missing.
- Impression or scan: The dentist records the prepared tooth and your bite so the crown can be made to fit. In a conventional process, a temporary crown protects the tooth while a dental laboratory makes the final one.
- Fitting: At a later visit, the dentist checks the permanent crown’s fit, color, and bite and then cements it. Some practices can make and place a crown in one appointment using in-office digital equipment. Whether that is suitable depends on the case.
Ask about the planned number of visits and what to do if a temporary crown comes loose. Preparation can leave the tooth sensitive for a while. Your dentist can explain what to expect for your own treatment.
How long does a crown last?
Crowns eventually may need repair or replacement. Cleveland Clinic gives an average lifespan of roughly five to 15 years, with substantial variation. The material, fit, tooth position, grinding habits, and daily care all matter. Brush twice a day with fluoride toothpaste, clean between your teeth, and keep regular dental appointments. Avoid using your teeth to open packaging or chew hard objects. If you grind your teeth, ask whether a night guard is appropriate.
When should you call the dentist?
Contact your dentist if a crown feels loose, chips, changes your bite, or causes persistent pain or sensitivity. If it falls off, keep it and call the dental office for instructions; do not try to attach it with household glue. Severe swelling, fever, or trouble swallowing warrants prompt medical or dental attention.
Questions to ask before treatment
- Why is a crown recommended for this tooth, and what alternatives are reasonable?
- Which material do you recommend, and why?
- How many visits are expected, and will I need a temporary crown?
- What will the total fee include, and what might my dental insurance cover?
