Dental Implants Must Have

3 days ago
I purchased this model on April 1 2025 because it has the right tools to effectively clean my dental implants and it has a large water tank and it plugs in so there's no need to recharge the unit. It is easy to operate, you can also adjust the speed of it's water flow which is a plus so the only negative is it is loud side but other than that I will keep using it for my oral health as it seems to be quite an effective tool in extending the my oral health. Happy with purchase!!!

Excellent Purchase!

I had to start out at 5-6 then go up to 7 as my gums were not ready for 10! I love my WaterPik! Leaves my gums and in between my teeth cleaner than before! Of course, nothing replaces flossing, but this has helped me so much, especially with my crowns! Even my dentist recommends it!

Yes, I recommend this product.
