Hydration is the Secret to Good Oral Health

Summer is herWoman sipping a glass of watere, which means you’re probably spending more time outdoors to enjoy the warm weather. As you soak up the sun, don’t forget to drink plenty of water. Dehydration can affect your oral and general health. Here’s how staying hydrated can support healthy teeth and gums.

Dehydration Causes a Dry Mouth

You probably don’t spend much time thinking about your saliva, but a normal body produces 2 to 4 pints of spit each day. Saliva not only kick-starts the digestive process, but it also keeps your mouth moist. Dehydration decreases your saliva production, causing your mouth to become dry. A dry mouth is a perfect environment for oral bacteria growth, which can increase your risk of certain dental issues, including:

  • Tooth Decay: Tooth decay occurs when the enamel is exposed to cavity-causing bacteria. Your saliva rinses food residue from your teeth to keep decay at bay.
  • Gum Disease: Gum disease is caused by bacteria found in plaque and tartar buildup. If your mouth is too dry, bacteria can get out of control quickly, causing red, swollen, and bleeding gums.
  • Bad Breath: An overgrowth of bacteria can lead to chronic bad breath, no matter your oral hygiene routine.

Brushing and flossing can remove oral bacteria, but a dry mouth isn’t something to ignore. Staying hydrated is your first step to improving the health of your teeth and gums.

Hydration Supports a Healthy Smile

Healthcare professionals recommend drinking at least eight 8-oz glasses of water each day to prevent dehydration. However, the amount necessary varies depending on various factors, like if you’re outdoors or physically active, which means you need to drink more water. 

Staying hydrated will keep your mouth moist to control oral bacteria. With every sip you take, you replenish your body’s water supply and rinse your mouth, which will decrease oral bacteria.

If drinking more water doesn’t resolve a dry mouth, it’s time to contact your dentist. Besides dehydration, various factors can cause the issue, like certain medications or underlying health problems. Your dentist will determine what’s causing the decrease of saliva production to create a personalized treatment plan to support a healthy smile. 

You can do many things at home to encourage saliva production, like chewing a piece of sugarless gum or eating low-fat cheese. With a proactive approach to combating dry mouth, your smile will stay healthy.

I've been coming to this practice for years now since moving to the Raleigh area. The office is always clean and organized and the staff have always been friendly and communicative. Also, the TV's mounted to the ceiling are a nice touch! I've been seeing Dr. Laster for several years before our insurance changed causing me to change to Dr. Rensch. Both are so easy to talk to and always made me feel at ease.

From beginning to end 5/5! I thought I was experiencing a dental 911. I submitted an inquiry at 11:30pm and by 8am the next morning, Deidra (front office staff) was already leaving me a message. She was so sweet and patient at 8am lol. After our initial conversation, I informed all follow up dentists “I found my dentist office” but thank you so much! Today I was welcomed with the same energy from Diedre to Britany then finally Dr.Wrench. The music playing throughout the office was fantastic; ie music selection and volume. The TV’s on the ceiling and wall made my procedure so painless and enjoyable! I watched an entire Christmas movie lol! Dr. Wrench (apologies for spelling) made my teeth absolutely perfect! I left telling my friends and family I have a million dollar smile! 😊 I can tell he wanted them perfect and he did! Thank you all so much for being amazing! Sincerely, Your next patient.

Dr. Laster and Dr. Rensch go above and beyond for their patients. I have seen both for various treatments and I always feel comfortable and heard. They take time to listen and to talk with you. They explain your options and work with you to develop the best plan for your care. They are always upbeat and positive and you can tell they truly love what they do. The front desk staff is exceptional as well. Deidre is so caring and very sweet. She’s efficient, understanding and conscientious of your time. I highly recommend.

Connections Dentistry was great! The staff is so friendly and truly cares about their patients. My appointment was quick, and honestly the best dental experience I’ve had. They are great about offering helpful solutions without making you feel like you are being reprimanded… which was the reason I was putting off the dentist. 100% recommend!
