Having a dental crown fitted is a significant step in restoring a damaged or weakened tooth, and it is entirely natural to have questions about what happens afterwards. Many patients leave their appointment feeling unsure about what they can eat, how to clean around the crown, or whether any discomfort they experience is normal. This uncertainty often leads people to search online for guidance in the days and weeks following treatment.
Understanding what to avoid after getting a new crown is just as important as understanding the treatment itself. Whether your crown was placed to protect a tooth following a root canal, restore a fractured tooth, or improve the appearance of a worn tooth, the aftercare guidance remains broadly similar. Proper care in the initial period — and in the long term — can make a meaningful difference to how well your crown performs over time.
This article explains what to avoid with a new dental crown, why certain precautions matter, and when it may be appropriate to seek further dental advice.
After receiving a new dental crown, you should avoid hard, sticky, and chewy foods — particularly in the first 24 to 48 hours. You should also avoid chewing on the crowned side if sensitivity is present, grinding your teeth, and skipping your daily oral hygiene routine. Caring carefully for your new crown supports its longevity and helps protect the tooth underneath.
A dental crown is a tooth-shaped cap that is cemented over a prepared natural tooth. Crowns are used for a variety of clinical reasons, including restoring teeth that are significantly decayed, cracked, or broken, protecting teeth following root canal treatment, and in some cases improving the appearance of a discoloured or misshapen tooth.
Crowns can be made from several materials, including porcelain, ceramic, metal alloys, or a combination of these. The choice of material depends on clinical factors such as the location of the tooth, the forces it will experience during biting and chewing, and aesthetic considerations.
Once a crown is cemented in place, it acts as a protective layer over the underlying tooth structure. However, the crown itself is not indestructible. Like natural teeth, it can be subject to damage from excessive force, poor oral hygiene, or certain habits. Understanding this helps explain why particular behaviours should be avoided following crown placement.
If you are considering restorative dentistry and would like to understand which options may be suitable for your circumstances, learning about dental crowns and tooth restoration can provide a helpful starting point before your consultation.
The first 24 to 48 hours following crown placement are particularly important, especially if a temporary crown is still in place awaiting a permanent one.
Hard foods: Biting down on hard items such as nuts, crusty bread, raw vegetables, or hard sweets places significant pressure on a newly cemented crown. This can dislodge or crack the crown before the cement has fully set or before you have adjusted to the feel of the restoration.
Sticky or chewy foods: Toffee, chewing gum, caramel, and similar foods can pull at a crown and, in some cases, lift it away from the tooth — particularly with temporary crowns, which use a weaker cement by design.
Chewing on the crowned side: If sensitivity or discomfort is present, your dentist may advise you to favour the other side of your mouth while you adjust.
Hot and cold extremes: Sensitivity around a newly crowned tooth is not uncommon. Extremely hot or very cold food and drinks may exacerbate this sensitivity in the short term.
Alcohol-based mouthwashes immediately after treatment: Some dental cement can be temporarily softened by alcohol. Your dentist will advise you on when it is appropriate to resume use of these products.
Once your crown is fully settled and you have returned for any necessary follow-up, there are ongoing habits to be mindful of to protect the restoration over time.
Teeth grinding or clenching (bruxism): This is one of the most significant risks to a dental crown's longevity. Grinding places excessive and repetitive force on the crown, which can cause it to crack, chip, or wear down prematurely. If you are aware that you grind your teeth — particularly at night — it is worth discussing the possibility of a custom-made occlusal splint with your dentist.
Using your teeth as tools: Opening packaging, biting nails, or holding objects between your teeth are habits that place unnecessary stress on all teeth, including crowned ones.
Chewing ice: Ice is harder than it appears, and repeatedly chewing it can fracture both natural teeth and crowns.
Neglecting flossing: Some patients worry that flossing around a crown will dislodge it. When done correctly, flossing is safe and important. Your dentist or hygienist can demonstrate the correct technique to clean around the margins of your crown without causing harm.
Ignoring changes in your bite: If something feels different about how your teeth meet after crown placement, this should be reported to your dental team. An uneven bite left uncorrected can create undue pressure on the crown.
To appreciate why these precautions matter, it helps to understand what is happening at the tooth and crown level.
When a tooth is prepared for a crown, a portion of the outer enamel is removed to allow the crown to sit correctly and look natural. This means the prepared tooth underneath relies on the crown for its protection. If the crown is damaged or dislodged, the prepared tooth is potentially more vulnerable than it was before treatment.
The dental cement used to secure a crown creates a strong bond, but this bond can be compromised by excessive force, particularly in the early period after placement. Over time, the cement seal around the margin of a crown — the point where the crown meets the natural tooth at the gumline — can also degrade. This is one reason why maintaining good oral hygiene around crowns is important: bacteria can potentially enter through a weakened margin and cause decay in the underlying tooth structure, a process sometimes referred to as secondary or recurrent decay.
Porcelain and ceramic crowns, while highly aesthetic, can be more susceptible to chipping under sudden impact compared to metal-based crowns. This is why the type of crown you have may also influence the aftercare advice your dentist provides.
Maintaining thorough oral hygiene is one of the most important aspects of caring for a new crown — and an area that is important not to overlook.
Brushing: Brush twice daily using a soft-bristled toothbrush and fluoride toothpaste. Pay particular attention to the gumline around the crown, as plaque accumulation in this area can contribute to gum inflammation and potential decay at the crown margin.
Flossing: Floss daily around the crown. When removing floss, slide it out from between the teeth rather than lifting it upwards, which reduces the risk of catching on the crown.
Interdental brushes: Your dental hygienist may recommend interdental brushes as an alternative or supplement to flossing, depending on the spacing around your crown and adjacent teeth.
Mouthwash: A fluoride mouthwash used at a separate time to brushing can provide additional protection for the tooth margins. Your dentist or hygienist can recommend a suitable product for your needs.
Regular professional cleaning supports the long-term health of crowned teeth. A dental hygiene appointment can help maintain clean crown margins and healthy surrounding gum tissue.
Beyond the immediate post-placement period, most patients with settled, permanent crowns can return to a relatively normal diet — but with some ongoing awareness.
Foods to approach with caution long-term:
Foods that are generally suitable:
Beverages: Heavily sugary or acidic drinks can contribute to decay at the crown margins and should be consumed in moderation as part of an overall balanced approach to oral health. Water remains the most protective choice for maintaining dental health throughout the day.
It is worth noting that individual circumstances vary. Your dentist should tailor aftercare guidance to your specific situation, the type of crown fitted, and the condition of your surrounding teeth.
There are situations following crown placement where contacting your dental practice is advisable.
Persistent pain or sensitivity: Some initial sensitivity after crown placement is normal and typically settles within a few days to a couple of weeks. However, if pain or sensitivity persists beyond this period, or if it is significant, a further assessment may be needed to check the fit and comfort of the crown.
Crown feeling loose or dislodged: If your crown feels loose, shifts when you bite, or comes off entirely, contact your dental practice. A dislodged crown should be kept somewhere safe and brought to your appointment.
Changes to your bite: If your bite feels uneven or uncomfortable, this should be reviewed by your dentist, as an incorrect bite can cause strain on the crowned tooth and surrounding structures.
Swelling or gum changes around the crown: Any swelling, redness, or changes to the gum tissue around the crown margin warrants a professional assessment.
Visible damage to the crown: Chips, cracks, or visible wear on the crown surface should be assessed by your dentist to determine whether the crown needs repair or replacement.
Symptoms are best reviewed in the context of a clinical examination, as the appropriate response will depend on individual circumstances. If you are experiencing any of the above, it is sensible to get in touch with a dental professional to arrange an assessment.
With the right habits, a well-maintained dental crown can function effectively for many years. The following practical steps support long-term crown health:
Prevention is generally preferable to further treatment. Consistent, conscientious care gives your crown a strong opportunity to function well over time.
It is common to experience some sensitivity or mild discomfort around a newly crowned tooth for a few days following placement. This typically settles as you adjust to the restoration. Sensitivity to temperature — particularly cold — can sometimes persist for a couple of weeks. If sensitivity is significant, worsening, or continues beyond two weeks, it is advisable to contact your dental practice for a review. The cause and appropriate response will depend on the individual clinical situation.
In the immediate period after crown placement, it is advisable to avoid hard, sticky, and chewy foods until the dental cement has fully set and any localised sensitivity has subsided. Once your permanent crown is settled and your bite feels comfortable, most patients are able to return to a largely normal diet, with ongoing awareness around particularly hard or sticky foods. Your dentist can provide specific guidance based on the type of crown placed and your individual circumstances.
If your bite feels uneven or your crown feels higher than your surrounding teeth when you close your mouth, this usually means the crown needs a minor adjustment to ensure proper occlusion (the way your teeth meet). This is a relatively straightforward matter for your dentist to correct and should be addressed promptly, as an uneven bite can cause discomfort or place excess pressure on the crowned tooth. Contact your dental practice to arrange a review appointment.
While it is not a common occurrence with a well-fitted and properly cemented permanent crown, crowns can occasionally become dislodged — for example, due to trauma, chewing very sticky foods, or degradation of the dental cement over time. If your crown comes off, keep it safe and contact your dental practice as soon as possible. Avoid attempting to reattach it yourself. The underlying tooth may need assessment before recementation or replacement.
Cleaning around a dental crown involves the same fundamental principles as general oral hygiene. Brush twice daily with a soft-bristled toothbrush and fluoride toothpaste, paying attention to the gumline where the crown meets the tooth. Floss daily — sliding the floss out sideways rather than snapping it upwards — to clean between the crown and adjacent teeth. Some patients find interdental brushes helpful. Your dental hygienist can demonstrate the most effective technique for your specific crown and oral anatomy.
The lifespan of a dental crown varies depending on factors including the material used, its position in the mouth, the forces it is subjected to, and the quality of home care and professional maintenance. With good oral hygiene, regular dental check-ups, and conscientious habits, many crowns can function well for ten years or more. However, individual outcomes vary, and no specific lifespan can be guaranteed. Your dentist can give you guidance based on the type of crown you have and your particular circumstances.
Caring for a new dental crown involves more than just avoiding certain foods in the first day or two. Understanding what to avoid with a new crown — both immediately after placement and as an ongoing commitment — gives your restoration a strong opportunity to function well and protect the tooth beneath it for the long term.
Good oral hygiene, mindful eating habits, and awareness of behaviours such as teeth grinding all play an important role. Regular check-ups allow your dental team to monitor the condition of your crown and address any concerns before they become more significant issues.
If you are experiencing persistent sensitivity, discomfort, or any changes to your crown, it is sensible to seek a professional opinion rather than waiting. Early assessment is generally preferable to delayed attention.
Dental symptoms and treatment options are best assessed individually during a clinical examination.
