I recently had the full-arch dental implant procedure done at Smith Dental, and I couldn't be happier with the results! From the initial consultation to the final follow-up, the entire experience was top-notch. Dr. Smith and his team were incredibly knowledgeable and caring throughout the process.

"Great dental experience. Modern equipment, and office. Staff is very friendly. I got in with no wait time. The teeth cleaning was painless to me...Doctor Warren and his hygienist explained all the pictures and what needed watching. All questions were answered. They listened to me. Looking forward to seeing them at least 3 times a year for more cleanings."

Frequently Asked Questions

How often should I floss?

You should floss at least once a day to maintain optimal oral health. This helps remove plaque and food particles from between your teeth and under the gum line, where a toothbrush can't reach.

What should I do about my tooth sensitivity?

For tooth sensitivity, use a toothpaste designed for sensitive teeth, avoid extremely hot or cold foods and drinks, and maintain good oral hygiene. If sensitivity persists, consult your dentist for a thorough examination and personalized treatment options.

What does fluoride do for my teeth?

Fluoride strengthens tooth enamel, making it more resistant to decay. It helps to prevent cavities by remineralizing areas of early decay and inhibiting the growth of harmful oral bacteria.

Is my bad breath related to my oral health?

Yes, bad breath can be related to oral health issues such as gum disease, tooth decay, or poor oral hygiene. Regular brushing, flossing, and dental check-ups can help manage and prevent bad breath.
