When Can You Drink Coffee After Teeth Whitening?


Teeth whitening is a popular cosmetic dental process that can enhance the appearance of your smile by reducing discoloration on your teeth. Many people who undergo this treatment are curious about when they can resume their daily habits, including enjoying a cup of coffee.

Coffee is a common culprit for tooth staining, and after investing in teeth whitening, it’s natural to want to maintain the results. In this post, we will explore the factors to consider and provide guidance on when it is safe to drink coffee after teeth whitening, ensuring you can strike a balance between your love for coffee and maintaining a bright, white smile.

Short-term Effects of Coffee on Teeth Whitening

It’s crucial to comprehend the short-term consequences coffee may have on the effectiveness of teeth whitening. The dark pigments and strong acidity of coffee are well-recognized for causing tooth discolouration. Here are some important things to think about:

1. Stain absorption: Your teeth may be more prone to absorbing stains after teeth whitening. The enamel’s pores are widened during the whitening procedure, making it simpler for chemicals like coffee to infiltrate and stain teeth.

2. Temporary sensitivity: Whitening your teeth might make your teeth more sensitive. Drinking hot or cold liquids, especially coffee, might exacerbate this sensitivity and make you feel uncomfortable immediately after teeth whitening.

3. Reversal of whitening effects: The effects of teeth whitening can be reversed by drinking coffee immediately after that, making your teeth appear less white. Coffee’s dark pigments have a tendency to stick to dental enamel, slowly discolouring it over time.

Our dentist in NE Calgary suggests choosing alternative liquids instead, like water or herbal tea and hold off on reintroducing coffee to your regimen until any temporary sensitivity subsides.

How Long Does it Take for Coffee to Harm Teeth Whitening Results?

It’s normal to be cautious of acts that can potentially compromise the effects of teeth whitening, such as drinking coffee. Although coffee can eventually discolour teeth, it may take a while for the benefits of teeth whitening to be adversely affected. Here are some things to consider:

  • Timing: Your teeth are more vulnerable to discolouration just after teeth whitening. To decrease the chance of staining and give your enamel time to shut its pores, it’s recommended to refrain from drinking coffee and other stains for at least 48 hours.
  • Frequency and consumption: Over time, your teeth are more likely to become stained with coffee if you drink it more regularly and in larger quantities. The effects of teeth whitening might be progressively lessened by frequent and excessive coffee drinking.
  • Oral hygiene techniques: Regular oral hygiene techniques, such as brushing and flossing after drinking stains like coffee, can help limit the negative effects on the outcomes of teeth whitening. Brushing your teeth can help erase coffee stains from their surface and lower their chance of permanent discolouration.
  • Personal factors: The composition of each person’s teeth and enamel might differ, impacting how rapidly stains appear. Coffee can leave stains on certain people that are more obvious than others.

Even though it’s a bit tricky to pinpoint a specific amount of time, it’s often advised to restrict or at least reduce coffee consumption to be safe. Furthermore, you may also want to think about using a straw. To lessen direct contact with the teeth.

Long-term Effects of Coffee on Teeth Whitening

Even though coffee is a popular beverage, it might have a long-term impact on the outcome of teeth whitening. Here are some crucial factors to remember:

1. Staining: Coffee includes chromogens, which are dark pigments that, over time, may cling to the enamel’s surface layer. Constant coffee intake can cause teeth to gradually get stained, diminishing the brilliance and whiteness attained with teeth-whitening procedures.

2. Enamel erosion: Since coffee is acidic, drinking acidic beverages often might cause enamel erosion. The entire health of the teeth may be jeopardized by tooth enamel erosion, which can also enhance tooth sensitivity and make teeth more vulnerable to discoloration.

3. Discolouration maintenance: Whitening your teeth is not a long-term fix. Teeth naturally become discoloured over time due to aging and exposure to various stains, including coffee. Regular coffee use might hasten the process of tooth discolouration and make it harder to maintain optimal whitening outcomes.

Finally, routine dental exams at our dentist can offer chances for expert cleaning and advice on preserving the results of teeth whitening.


While coffee is a popular and enjoyable beverage, you should ignore its impact on whitened teeth. Striking a balance between enjoying your favourite morning beverage and preserving your teeth whitening results requires conscious effort and preventive care. By taking proactive steps to protect your smile, you can continue to enjoy the benefits of teeth whitening.
