Hydration is always a crucial health topic and widely promoted as essential to medical well-being. Less commonly known, however, is why hydration is important for oral health. As we enter the warmer summer months, ensuring our bodies are well-hydrated becomes increasingly important. In fact, drinking water becomes even more critical for those over 55 as certain age-related changes increase the risk of dehydration.

If you do not take care to drink enough water each day, you may become dehydrated. Warning signs of dehydration include:
Urine that is dark yellow in color
Weakness
Low blood pressure
Dizziness
Confusion
In addition to protecting you from dizziness and illness, hydration also plays a crucial role in protecting your teeth and gums. Drinking enough water helps prevent tooth decay, reduces bad breath and keeps your smile strong.
5 Reasons Hydration is Key for Oral Health
Water washes away food and bacteria.
As you drink water, the water washes away leftover food and residue that bacteria in your mouth feed on, which eventually turns into plaque. Each swish of water helps remove food particles and debris in the mouth and thereby lowers the risk of tooth decay.
Of course, drinking water does not replace the need for proper oral hygiene routines. Every one, regardless of water intake, should continue the recommended daily habits of brushing twice a day for two minutes and flossing. Consider drinking water throughout the day as a hygiene sidekick that will help keep your smile cavity-free.
Water neutralizes acids.
Drinking water and staying hydrated significantly benefits oral health by neutralizing acids, preventing tooth decay, and promoting a healthy mouth. As water helps wash away food particles and bacteria that can lead to plaque buildup and bad breath, it also encourages saliva production, which is essential for neutralizing acids and protecting tooth enamel.
Staying hydrated prevents dry mouth.
Saliva is surprisingly important for maintaining your oral health. For starters, saliva helps fight decay by remineralizing your teeth with calcium, phosphate, and fluoride. Not producing enough saliva can lead to a condition known as dry mouth. Dry mouth is a serious oral health issue that can cause the tongue, gums, and other tissues to become painful and swollen. It also increases the risk of tooth decay and gum disease.
Drinking water helps produce saliva by providing the fluids necessary for the salivary glands to function properly. Sipping water throughout the day is one of the best ways to prevent dry mouth. Staying hydrated is one of the easiest ways to boost saliva production and enhance your oral health.
Fluoridated water strengthens your teeth.
Drinking fluoridated water is one of the easiest and most beneficial ways to prevent cavities. Fluoridated water strengthens teeth by restoring calcium and phosphorus levels in the dental enamel, making them more resilient against decay.
Water reduces staining.
Water is a natural cleanser that rinses away food after meals or between snacks. Many foods and drinks contain pigment that, when left resting on tooth enamel, can slowly cause discoloration and staining. Drinking water right after indulging in stain-causing foods or drinks, especially if you are unable to brush your teeth immediately, helps keep teeth whiter and stain-free.
Bottom Line: Drinking Water and Staying Hydrated Is Important for Protecting Your Oral Health
Drinking water is one of the simplest and most effective ways to protect your teeth. Water helps wash away food particles and boosts saliva production. Enjoying a glass of water from the tap also provides essential fluoride, which helps strengthen the enamel.
If you struggle to stay hydrated or drink water a sufficient amount of water, follow these tips to build healthy hydration habits (yes, we've shared these before...but they're so important we wanted to share again).
Tips for staying hydrated:
Consider purchasing a thermos or water bottle to keep with you throughout the day.
Monitor your intake and stay accountable with a friend or loved one who is also committed to self-care.
Dress up your plain water and stay hydrated with a healthy "mocktail" by adding natural garnishes such as cucumber, lemon, orange or mint.
