Should You Do a Mouth Rinse After Brushing Your Teeth?

When it comes to regular dental care, you probably know the basics: brush your teeth twice daily and floss at least once daily. However, where do mouth rinses fit in this picture? After all, many people (perhaps even you) rinse their mouths with water after finishing the toothbrushing process. Is this good for your oral health, or is it something you should avoid? To learn the answer, read this summary of mouth rinsing’s effects on dental hygiene by your Raleigh dentist.

Positive Effects, or ‘The Case for Rinsing’

First of all, a post-brushing rinse often feels natural. Sensing leftover toothpaste in one’s mouth is sometimes unpleasant. Plus, not rinsing leaves you with an aftertaste that you’d rather replace with something neutral. In other words, the practice fulfills a bodily urge.

Rinsing could also prevent harmful health risks. Namely, you’re more likely to ingest too much fluoride from toothpaste if you don’t. This excess could then cause side effects like nausea, diarrhea, and abdominal pain.

Negative Effects, or ‘The Case Against Rinsing’

On the other hand, rinsing right after brushing could undo the latter’s benefits. The fluoride in toothpaste works best when it stays on your teeth for several minutes. Swishing and spitting water from your mouth would remove that mineral before it could boost your oral health.

This negative impact could also apply to rinses with mouthwash. Even if the brand you use has fluoride, toothpaste has more concentrated forms. Rinsing with mouthwash straight after brushing may wash away this more concentrated type.

What’s the Right Choice?

There isn’t a hard rule among dentists on whether or not to rinse; it ultimately depends on your situation. For instance, if you’re prone to tooth decay, you may want to skip rinsing so that your teeth have a fluoride coating. Meanwhile, rinsing could be good if you want to remove plaque after flossing.

Whatever you end up choosing, just remember to practice proper oral hygiene every day. That means brushing, flossing, and getting dental checkups regularly.

If you’re still curious or concerned about mouth rinses, get the opinion of your local dentist. They’ll be glad to offer you help!

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!
