Crowns can be placed on natural teeth or on dental implants. Although they may look the same, they are attached differently and have different maintenance needs. Understanding these differences helps you care for each type properly.
A crown on a natural tooth is cemented or bonded onto the prepared tooth. An implant crown is attached to an abutment connected to the implant, either with cement or a screw.
Natural teeth have a ligament that provides slight cushioning and sensation. Implants are fused directly to bone, so they feel slightly different when biting.
Natural teeth under crowns can develop decay at the margins. Implants cannot decay but can develop inflammation and bone loss around them.
Both require daily brushing and cleaning between teeth. Implant crowns may need special cleaning tools and regular checks of screws and gum health.
Screw-retained implant crowns can be removed for repair or cleaning. Natural tooth crowns usually need to be cut off if they need replacement.
Both can last many years with good care. Regular check-ups help detect issues early.
Both types of crowns can be made from zirconia, lithium disilicate or porcelain fused to metal. For implant crowns, strength is often prioritised because implants do not cushion biting forces, so zirconia is popular. Crowns on natural teeth at the front of the mouth may use more translucent materials for a natural look. Your dentist will choose materials that suit the position of the tooth, your bite and your appearance goals, aiming for crowns that blend seamlessly with your smile.
A crowned natural tooth still has living tissue inside unless it has had root canal treatment, so it can become sensitive to hot or cold or ache if decay develops under the crown. An implant crown has no nerve, so it will not feel sensitive, but this also means problems may not cause pain. Bleeding, swelling, a bad taste or a loose feeling around an implant are the main warning signs. Because implants can develop problems silently, regular check-ups and periodic X-rays are especially important.
Natural teeth can move very slightly when you bite, thanks to the ligament that surrounds their roots. Implants cannot, so they absorb biting forces differently. Your dentist will carefully adjust the bite on an implant crown so it does not take excessive force. If you grind or clench your teeth, a night guard can protect both implant crowns and natural tooth crowns from chipping, screw loosening and wear. Mention any grinding or jaw ache to your dentist so it can be managed early.
Crowns on natural teeth and on implants both eventually wear and may need replacement. Natural tooth crowns are usually replaced if there is decay, a broken edge or a poor fit. Implant crowns may be replaced if the porcelain chips or the gum level changes. Screw-retained implant crowns can often be removed without damage, making replacement or repair easier. Your dentist will discuss the most appropriate approach based on the type of crown and the reason for replacement.
They may feel slightly different because they lack the cushioning ligament of natural teeth.
No, but the gum and bone around implants can become inflamed.
Both can last many years with proper care.
