Teeth whitening is a popular cosmetic dental treatment that can transform your smile, giving you a brighter and more confident appearance. However, many patients wonder how long they need to wait before they can eat normally after undergoing this procedure. The short answer? It depends on the method used and your dentist’s recommendations.
In this blog, we’ll discuss what happens to your teeth after whitening, why your diet matters during the recovery period, and how to care for your teeth to maintain your sparkling new smile.
What Happens to Your Teeth After Whitening?
Teeth whitening treatments work by removing stains and discolouration from the enamel. Whether you choose professional in-office whitening or at-home whitening kits provided by your dentist, the procedure involves using bleaching agents such as hydrogen peroxide or carbamide peroxide.
During the whitening process, your teeth become slightly more porous. This temporary change makes them more susceptible to staining, which is why your post-whitening diet is so important. The porous nature of the enamel will return to normal within 24 to 48 hours, but during this time, you’ll need to avoid certain foods and drinks.
How Soon Can You Eat After Teeth Whitening?
After teeth whitening, you can eat, but your choices should be limited to specific foods. Most dentists recommend following a “white diet” for at least 24 to 48 hours. This means sticking to foods and drinks that are light in colour and non-acidic, which reduces the risk of staining or causing sensitivity.
If you’ve had professional whitening done, your dentist will provide you with clear aftercare instructions tailored to your treatment.
The First 24-48 Hours: Foods You Should Avoid
The first 24 to 48 hours after whitening are critical for ensuring your results last. Here are the main culprits to avoid during this period:
1. Dark-Coloured Foods and Drinks
- Coffee, tea, and red wine are the biggest offenders, as their dark pigments can easily stain teeth.
- Fizzy drinks, including cola, should also be avoided due to their acidity and artificial colouring.
- Foods like tomato-based sauces, curry, soy sauce, and chocolate can cause discolouration.
2. Acidic Foods
- Oranges, lemons, and other citrus fruits can erode enamel and cause discomfort, especially if your teeth are sensitive after whitening.
- Vinegar-based dressings and pickles should also be avoided.
3. Strongly Pigmented Foods
- Beetroot, berries (such as blueberries and blackberries), and colourful spices like turmeric can leave stains.
- Avoid brightly coloured sweets or lollies, which may also contain artificial colouring.
4. Hot or Cold Foods
- Extremely hot or cold foods can aggravate sensitivity. Stick to room-temperature meals until any sensitivity subsides.
What Foods Can You Eat After Teeth Whitening?
While it might feel restrictive, there are plenty of foods you can safely enjoy after whitening. These options are gentle on your teeth and won’t interfere with the results:
1. White or Light-Coloured Foods
- Boiled potatoes, white rice, and plain pasta are excellent choices.
- Skinless chicken, turkey, or white fish are protein-rich and won’t stain your teeth.
2. Dairy Products
- Yoghurt, milk, and cheese are great options as they are light in colour and can help neutralise acids in the mouth.
- Soft cheeses like mozzarella are especially safe to eat.
3. Soft Fruits
- Bananas and peeled apples are gentle on teeth and light in colour.
4. Plain Snacks
- Crackers, bread (without coloured spreads), and plain popcorn are safe to consume.
These foods are not only tooth-friendly but also help keep your teeth healthy while you’re adjusting to your newly whitened smile.
When Can You Return to a Normal Diet?
Most people can resume their normal diet 48 hours after whitening. By this time, the enamel’s porosity has stabilised, making it less prone to staining. However, it’s always wise to maintain some level of caution. Reducing your intake of foods and drinks that are notorious for staining, such as coffee and red wine, can help prolong the effects of your treatment.
If you’re unsure whether a particular food or drink is safe, err on the side of caution or consult your dentist at Sherwood Park Dental Practice for advice.
Tips to Maintain Your Bright Smile
Following your teeth whitening treatment, adopting good oral care habits can help extend the results. Here are some practical tips:
1. Brush and Floss Daily
Brush your teeth twice a day using a non-abrasive toothpaste to prevent plaque build-up. Flossing helps remove debris from between your teeth, which can reduce the risk of staining.
2. Rinse Your Mouth After Eating or Drinking
If you can’t brush right away, rinsing with water after consuming dark or acidic foods can help reduce staining.
3. Use a Straw
For drinks like coffee, tea, or cola, using a straw can minimise contact with your teeth, reducing the risk of stains.
4. Avoid Smoking
Tobacco is one of the main culprits behind discolouration. Avoid smoking to keep your teeth white and healthy.
5. Schedule Regular Dental Cleanings
Professional cleanings can remove surface stains and maintain your smile’s brightness.
How to Handle Sensitivity After Whitening
Some patients experience temporary sensitivity following teeth whitening, which is perfectly normal. Here’s how to manage it:
- Use Desensitising Toothpaste: Products formulated for sensitive teeth can help ease discomfort.
- Avoid Hot or Cold Foods: Stick to room temperature meals to minimise irritation.
- Take a Break from Whitening Products: If you’re using at-home kits, give your teeth time to recover before starting another treatment.
If sensitivity persists, contact your dentist for further advice.
