Introduction
Having a dental crown fitted is a significant step towards restoring a damaged, weakened, or broken tooth. Whether yours was placed following root canal treatment, to protect a heavily filled tooth, or to improve your smile's appearance, it is entirely natural to have questions about what happens next — and what you should and shouldn't do in the days and weeks that follow.
Many patients search online after their appointment because they want reassurance. They want to know whether the sensitivity they're feeling is normal, which foods are safe to eat, and whether their daily habits might put their new crown at risk. These are all very reasonable concerns.
Caring for a new crown properly in the early stages can make a meaningful difference to how well it settles and how long it lasts. This article will explain what to avoid after having a dental crown fitted, why certain habits can affect your crown's integrity, and when it may be worth contacting your dental team for advice.
Featured Snippet: What Should You Avoid Doing With a New Crown?
What should you avoid doing with a new crown?
After receiving a dental crown, you should avoid hard, sticky, and chewy foods — particularly in the first 24 to 48 hours. Avoid habits such as teeth grinding, nail biting, and chewing on non-food items. Do not skip oral hygiene around the crown, and contact your dentist if you experience persistent pain, sensitivity, or a change in your bite.
Why Dental Crowns Need a Little Extra Care at First
A dental crown is a custom-made cap that fits over a prepared tooth, restoring its shape, strength, and function. Crowns can be made from a range of materials, including porcelain, ceramic, metal alloy, or a combination of these. The choice of material often depends on the location of the tooth, the forces it will need to withstand, and your personal preferences, all of which your dentist will discuss with you during your consultation.
Once a crown is cemented into place, it typically needs a short settling period. During this time, the tooth and surrounding gum tissue may feel slightly sensitive or tender, which is a normal part of the adjustment process. The cement used to secure the crown also needs adequate time to fully set.
Understanding why your crown needs careful attention in the early stages helps put the post-treatment guidance you receive into context. A crown is a precision-engineered restoration — protecting it from undue stress, particularly at the start, gives it the best chance of performing well over the long term.

Foods and Drinks to Avoid After a New Crown Is Fitted
One of the most common questions patients ask after having a crown fitted is: "What can I eat?" The answer depends partly on whether you have a temporary or permanent crown, but there are general guidelines that apply to both.
In the first 24 to 48 hours, it is advisable to stick to soft foods and to avoid placing unnecessary pressure on the crowned tooth. The dental cement needs time to fully cure, and eating challenging foods too soon can disrupt this process.
Foods and drinks to be cautious about include:
- Hard foods such as crusty bread, raw carrots, hard sweets, and nuts — these can exert excessive force on a new crown and, in some cases, crack or dislodge it
- Sticky foods such as toffee, chewing gum, and certain dried fruits — these can pull at the crown and potentially loosen the cement bond
- Chewy foods such as bagels, tough meats, or chewy sweets — these place sustained pressure on the restoration
- Very hot or very cold foods and drinks — temperature sensitivity is common after crown placement, and extremes may cause temporary discomfort
- Hard ice — a particularly common culprit for damaging both natural teeth and restorations
You do not need to avoid these foods permanently in most cases, but being mindful of them — especially in the early days — is a sensible precaution.
Habits That Can Damage a New Crown
Beyond food choices, certain everyday habits can place your new crown under unnecessary strain. Being aware of these can help you protect your restoration and avoid the need for early repair or replacement.
Teeth Grinding and Clenching (Bruxism)
Teeth grinding, known clinically as bruxism, is one of the most significant threats to dental crowns. Many people who grind their teeth do so during sleep, making it difficult to be aware of the habit. The repeated force applied during grinding can crack, chip, or loosen a crown over time — even a well-fitted one.
If your dentist has indicated that you may be grinding your teeth, they may recommend a custom-made night guard or occlusal splint to protect your teeth and restorations while you sleep. This is a straightforward, non-invasive way to help protect the investment you have made in your dental health.
Nail Biting and Chewing Non-Food Items
Biting your nails, chewing on pen lids, or using your teeth to open packaging are habits that many people do automatically and without thinking. These behaviours apply irregular and unpredictable forces to your teeth and restorations, and are worth trying to avoid — not just for your crown, but for your general dental health.
Using Your Teeth as Tools
Opening bottles, tearing labels, or tearing tape with your teeth are common habits that can dislodge or damage crowns. It is always safer to use the appropriate tool for the task.
The Dental Science Behind Why Crowns Can Become Loose or Damaged
Understanding a little about the structure of a dental crown helps explain why certain activities pose a risk.
A crown is secured to the underlying prepared tooth — known as the abutment — using dental cement. This cement forms a seal between the crown and the tooth, helping to prevent bacteria from entering the space beneath the restoration. When the seal is intact and the crown fits well, it is a highly effective restoration.
However, the cement bond, whilst strong, is not indestructible. Excessive or repetitive force — from grinding, hard foods, or accidental impact — can gradually weaken the bond or cause the crown material itself to fracture. Porcelain and ceramic crowns, though natural-looking and durable, can be susceptible to cracking under sudden or extreme force, in much the same way as a ceramic plate might crack.
Additionally, if bacteria manage to penetrate beneath a crown — perhaps because the seal has been compromised or because oral hygiene in the area has been inadequate — decay can develop on the remaining natural tooth structure underneath. This is why good oral hygiene around the crown margin (where the crown meets the gum) is so important.
Oral Hygiene Around a New Crown — What You Should Do
Whilst this article focuses on what to avoid, it is equally important to understand what you should continue doing after a crown is fitted — namely, maintaining thorough and consistent oral hygiene.
Brushing should continue twice daily using a fluoride toothpaste. Use gentle, circular motions and ensure you clean the area where the crown meets the gumline. Avoid scrubbing aggressively, as this can cause gum irritation over time.
Flossing is equally important and should not be neglected simply because a crown is present. Use a gentle sliding motion to guide floss between the crowned tooth and its neighbours, being careful not to snap it down onto the gum. Interdental brushes or a water flosser can be useful alternatives if standard floss is difficult to use in certain areas.
Antibacterial mouthwash can be a helpful addition to your routine, although it is not a replacement for brushing and flossing. Your dentist will advise on whether a specific mouthwash is appropriate for you.
Good oral hygiene around a crown is one of the most effective ways to extend its lifespan and protect the underlying tooth. You can learn more about maintaining excellent preventive dental care on our website.
When Professional Dental Assessment May Be Needed
After a crown is fitted, some degree of sensitivity and mild discomfort is entirely normal and usually settles within a few days to a couple of weeks. However, there are certain signs that would warrant a conversation with your dental team.
You may wish to contact your dentist if you experience:
- Persistent or worsening pain that does not improve after a few days
- Sharp pain when biting — this may suggest the crown is sitting slightly high and affecting your bite, which is a straightforward adjustment your dentist can make
- Sensitivity to temperature that is severe or does not ease with time
- Visible cracks or chips in the crown material
- The crown feeling loose or moving when you bite
- Swelling, redness, or tenderness in the gum tissue around the crown
- A crown that has become fully dislodged
None of these situations should cause undue alarm, but they do all benefit from professional review. Your dentist can assess whether any adjustment, repair, or further treatment is needed. Please remember that it is always better to seek advice early rather than waiting for a problem to progress.

Prevention and Long-Term Crown Care
With proper care, a well-fitted dental crown can last for many years. There are practical steps you can take to help protect it over the long term.
Attend regular dental check-ups. Your dentist will examine your crown at each routine appointment, checking the fit, the cement seal, the condition of the crown material, and the health of the surrounding gum and bone. Regular professional cleaning also helps remove tartar from around the crown margin, where it can accumulate.
Wear a night guard if advised. If you have a tendency to grind or clench your teeth, a custom-fitted night guard is one of the most effective ways to protect your crowns and natural teeth from excessive wear.
Be mindful of your dietary habits. Whilst you do not need to permanently restrict what you eat, being thoughtful about very hard or very sticky foods will help extend the lifespan of your restoration.
Avoid tobacco products. Smoking and chewing tobacco can affect gum health and contribute to gum recession, which over time may expose the crown margin and increase the risk of decay or sensitivity.
Communicate with your dentist. If something feels different about your bite, if you notice sensitivity, or if anything about the crown concerns you, mention it at your next appointment — or contact the practice sooner if symptoms are significant.

Frequently Asked Questions
How long does it take to get used to a new dental crown?
Most patients find they adjust to a new crown within a week or two. Mild sensitivity, a slight awareness of the crown, or minor changes to how your bite feels are all common in the early days. If you notice that your bite feels significantly different — for example, if you are biting on the crown before your other teeth — let your dentist know, as a small adjustment to the crown's height can usually resolve this quickly and comfortably.
Can I eat normally immediately after having a crown fitted?
It is generally advisable to wait at least a few hours after your appointment before eating, particularly if you have had local anaesthetic, as your mouth may still be numb. For the first 24 to 48 hours, softer foods are recommended to allow the cement to fully set. After this initial period, most patients are able to return to a normal diet, though being mindful of very hard or sticky foods on an ongoing basis is a sensible habit.
Is it normal for a crown to feel sensitive to hot and cold?
Yes, some temperature sensitivity is common after a crown is placed, particularly if the tooth had significant decay or had recently undergone root preparation. This sensitivity typically reduces over a few weeks. If the sensitivity is severe, persistent, or worsening rather than improving, it is worth contacting your dentist, as this may indicate the need for further assessment.
What happens if my crown falls off or becomes loose?
If your crown becomes loose or falls off, contact your dental practice as soon as possible. Avoid attempting to reattach the crown yourself using over-the-counter adhesives, as these are not intended for dental use and may complicate professional re-cementing. Keep the crown safe if it has come away completely, and your dentist will be able to assess whether it can be re-cemented or whether a new crown is needed.
How long should a dental crown last?
With good oral hygiene and regular dental care, dental crowns can last many years. The lifespan of a crown varies depending on the material used, the position of the tooth in the mouth, individual bite forces, and how well it is cared for over time. Your dentist will give you a realistic expectation for your specific crown during your consultation, though it is important to understand that no restoration can be guaranteed to last indefinitely. Individual outcomes vary.
Can decay develop under a dental crown?
Yes, it is possible for decay to form beneath a dental crown if oral hygiene in the area is not maintained or if the cement seal becomes compromised over time. The tooth structure underneath a crown is not immune to decay. This is one of the key reasons why brushing carefully along the gumline, flossing around the crown, and attending regular dental check-ups are all so important, even after a crown is in place.
Conclusion
A dental crown is a reliable and effective restoration that can significantly improve the function and appearance of a damaged tooth. Knowing what to avoid after your crown is fitted — from certain foods and drinks to habits that place unnecessary stress on the restoration — can make a meaningful difference to how well it performs and how long it lasts.
Caring for a new crown does not require dramatic lifestyle changes. It is largely about being mindful in the early days, maintaining consistent oral hygiene, and attending regular check-ups so your dentist can monitor the crown's condition over time.
If you ever have concerns about your crown — whether immediately after fitting or further down the line — do not hesitate to seek professional advice. Early assessment is almost always preferable to waiting.
