Prevent a white tongue and bad breath by hydrating, eating well, chewing gum, and brushing/scraping twice daily to protect taste and oral health.
1. Hydrating to Keep Your Tongue Pink and Healthy 💦
Drink plenty of water to prevent bad breath and keep your tongue hydrated.
A study was done on 50 participants, divided into 2 equal groups. Group A rinsed with 15ml of water for 30 secs, while group B drank 200ml of water within 30 secs.
Results showed that both groups had a significant reduction in volatile sulphur compounds. Both groups had a 30 – 50% reduction in hydrogen sulphide (H2 S) and a 60% reduction in methyl mercaptan (CH3 SH). This suggests that either drinking water or rising with water can have a good effect in washing away bacteria and reducing bad breath (Van der Sluijs et al., 2015).
It can also help wash away food particles and so limit the number of bacteria, as a surplus of bacteria is formed from leftover food particles left in our mouth.
Drink water regularly and after each meal to wash away all the food particles.
2. Tongue Healthy Foods 🍎
Don’t let your taste buds get accustomed to very sugary and salty foods as then regular healthy food will seem very boring and bland to eat.
By limiting your sugar and salt consumption, you will be able to taste the differences in many foods instead of always bombarding your taste buds.
Eating spicy foods won’t damage your taste buds, no matter how often you eat them, but switching to eating healthy vegetables like plain broccoli, kale or spinach might be harder to do.
Let your taste buds be accustomed to different flavours such as cheese, onion and garlic.
Obesity can weaken and lower the number of taste buds (Kaufman et al., 2018; Rohde et al., 2020)
Avoid or reduce your alcohol intake to avoid leukoplakia (white tongue) (Petti & Scully, 2006).
A diet rich in fruit and vegetables is inversely correlated to oral cancer risk, while a diet rich in animal fats and of animal origin is positively correlated (Scardina & Messina, 2012).

Drink matcha
Green tea polyphenols can help reduce mouth bacteria (Morin et al., 2015).
Chew Xylitol gum
Chewing dental gum containing xylitol can reduce mouth bacteria and also help produce saliva which can further wash away bacteria and food particles.
A study was done on 24 adults who chewed 10 pieces of xylitol chewing gum a day (6.2g of xylitol/ day). After 2 weeks results showed a 20% reduction in dental plaque. Bacteria associated with caries (tooth decay/cavities) decreased by 10.26% and two other types of bacteria associated with periodontitis decreased by 6.32% and 1.66% (Wu et al., 2022).
Eat Roma tomatoes
Lycopene can help exert protective effects against 4-nitroquinoline-1-oxide-induced tongue carcinogenesis (Scardina & Messina, 2012).
Oral candidiasis (Oral thrush)
Oral thrush is an infection of fungus in the mouth and is most visible on the tongue and inner cheeks as white lesions. It is usually common in people who use steroid sprays for asthma.
Unsweetened yoghurt may help with thrush.
There is a correlation between oral thrush and deficiency in beta carotene, (vitamins B1, B2, B9, C, K), zinc and carbohydrates (Scardina & Messina, 2012).
3. Gently Brush Your Tongue to Prevent White Coat 🪥
Gently brushing your tongue after brushing your teeth is just as effective at removing odour-causing mouth bacteria as a tongue scraper (Winnier et al., 2013).
4. Protecting Your Sense of Taste and Your Tongue 😛
Look out for any changes in your tongue’s colour, its colour should be pink.
Temperature burns
You may burn your tongue by drinking hot coffee, matcha or water. To avoid burns, wait 1- 2 minutes before taking a small sip.
Try drinking cold water if you have always been drinking warm or hot water as it can help you burn a small number of calories.
Avoid Smoking
Avoid all forms of smoking.
Mouth breathing
Don’t mouth breathe, breathe from your nose at all times. Mouth breathing can cause an increase in plaque levels over time and you may be 4 times more likely to develop the bacteria S. mutans which contributes to tooth decay (Mummolo et al., 2018).
