What does caring for a dental crown involve?
Caring for a dental crown means cleaning where the crown meets the gum, cleaning between neighbouring teeth, easing up on ice and very hard chewing on that side, and booking a review when something feels different. A dental crown is a custom cap fitted over a prepared natural tooth to restore shape and function after damage, decay or other treatment (healthdirect; Better Health Channel).
This page is about home care for a crown you already have. It is not a guide to choosing a new crown, not a price list, and not personal treatment advice. It sits apart from our guides on a filling that comes out, chewing ice, and a scale and clean, which are linked only as complements.
The Australian Dental Association states that having a crown does not mean no further treatment will ever be needed. Decay can still affect the tooth, and crowns can chip, fracture or need replacement over time (teeth.org.au). How long a crown lasts varies; daily care and regular checks matter.
How should I brush around the crown and gumline?
Focus on the join where the crown edge meets the gum. Plaque collects along that margin just as it does on natural enamel. Use a soft-bristled toothbrush with fluoride toothpaste twice a day, and use careful circular strokes along the gumline rather than scrubbing hard sideways (teeth.org.au; Better Health Channel).
Angle the bristles toward the gum so they reach the crown margin on both sides. Healthdirect notes that the crown surface itself does not decay, yet the tooth underneath still can (healthdirect).
AMK Dental Clinic does not promote toothbrush brands. If the gum beside the crown bleeds every time you clean, mention it at a check-up and clean.
How do I clean between teeth when I have a crown?
Brushing alone does not clean the contact between a crowned tooth and the teeth beside it. The Australian Dental Association recommends cleaning between teeth every day with floss or another interdental aid (teeth.org.au; teeth.org.au flossing).
Work the floss down the side of the crown, curve it into a C-shape, and slide it under the contact with controlled pressure — do not snap it onto the gum. Ask which interdental brush size fits if spaces are wider. See how to floss properly for technique.
If floss shreds, snags, or will not pass where it used to, that can mean a rough edge or a change in fit — a reason to book a review rather than ignoring the catch.
Why ease up on ice and very hard chewing?
A crown is cemented or bonded onto prepared tooth structure. Sudden hard force — crunching ice cubes, biting nutshells, or chewing other very hard objects on that side — can chip the crown or loosen the cement seal. Healthdirect lists a crown coming loose, breaking, chipping or cracking among possible complications (healthdirect).
Prefer sipping cold drinks and letting ice melt instead of biting cubes. See chewing ice and your teeth for the habit itself; here we only flag the load on an existing crown. If that tooth feels tender when you bite, chew on the other side until examined.
When should I book a review for a crown?
Book a dental review if you notice any of the following around a crowned tooth:
- The crown feels loose, mobile, or higher or lower than before when you bite
- A rough, sharp or catchy edge appears on the tongue or cheek side
- Floss catches, shreds or will not pass at the join where it used to slide
- Gums beside the crown stay sore or swollen, or bleed beyond the first days of a new cleaning routine
- Sensitivity to hot, cold or biting lingers rather than settling
Healthdirect lists looseness, chipping, decay around or under the crown, sore gums and a poor fit among possible problems (healthdirect). The Australian Dental Association likewise notes that crowned teeth can still decay and that crowns sometimes need replacement (teeth.org.au).
Do not glue a loose crown with household adhesive or file a rough edge yourself. Bring the crown if it has come off, and avoid chewing on that tooth until you are seen. If a filling has failed, use the filling comes out guide instead.

Common questions
Do I still need to clean around a crowned tooth?
Yes. A crown covers the tooth, but plaque still gathers where the crown meets the gum and on the tooth structure underneath and beside it. The Australian Dental Association advises brushing twice a day with fluoride toothpaste and cleaning between teeth every day. Healthdirect notes that the crown itself does not decay, yet the tooth underneath still can. Ask at AMK Dental Clinic in Mortlake if you are unsure about technique.
How should I clean between teeth next to a crown?
Clean between teeth at least once a day with floss, flossettes or interdental brushes, as the Australian Dental Association recommends. Slide floss carefully along the side of the crown and under the contact, rather than snapping it down onto the gum. If floss shreds, catches, or will not pass, that can be a reason to book a review. See our how-to-floss guide for technique, and ask which aid suits your mouth at AMK Dental Clinic.
Can I chew ice or hard foods on a crowned tooth?
Prefer not to crunch ice or other very hard objects on that side. Hard biting can chip or loosen a crown, and Healthdirect lists a crown coming loose, chipping or breaking among possible problems. Our chewing-ice guide covers the habit in more detail. Sip cold drinks and choose softer options when a crown already feels tender. Mention any new roughness at your next visit to AMK Dental Clinic in Mortlake.
When should I book a review for a crown?
Book if a crown feels loose or mobile, a rough or sharp edge appears, floss catches oddly at the join, gums around the crown stay sore or swollen, or sensitivity lingers when you bite or take hot or cold drinks. Healthdirect lists looseness, chipping, decay around or under a crown, and gum swelling as reasons problems can arise. Call AMK Dental Clinic on (02) 9739 6525 or use the contact page.
Is this the same as fixing a lost filling or having a scale and clean?
No. This page is about daily home care for a crown that is already in place. If a filling has come out, follow our filling guide. A scale and clean is a professional clean of teeth and gums, described in our scale-and-clean post. Crown home care sits alongside those topics rather than replacing them. For booking steps at AMK Dental Clinic in Mortlake, see how to book an appointment.
