When you understand how to take great care of your mouth, you are much more likely to keep it in tip-top shape.

Preventive Dentistry

Prevention is always less costly and more effective than treating an issue that has had a chance to take hold in your mouth.

Non-Surgical Gum Treatment

Non-surgical gum treatment, also known as scaling and root planing can help to prevent inflammation of the gums once periodontitis has taken hold of your gums.

Oral Hygiene

Having great oral hygiene is the most important part of preventing oral health issues from occurring. Brushing and flossing at least twice a day is important to keep your mouth happy and healthy.


Sometimes, when teeth become very damaged or decayed, it becomes imperative that you have the tooth removed to prevent the spread of infection to the surrounding teeth and gums. Tooth extractions are a routine dental procedure.


Mouthguards are important for those who participate in highly physical sports. Having a custom-made mouthguard can protect your teeth from damage and give you the peace-of-mind you deserve. Brux guards are important if you find yourself grinding your teeth are night, or if you snore.


Lots of bacteria live in your mouth and feed on the foods that you eat, which is why brushing and flossing are so important. For those times when brushing and flossing are missed, we provide fillings, to take care of cavities that form.

Restorative Dentistry

Breathing new life into old teeth is a big part of what we do here at Goichi Shiotsu, DDS. We think it’s important for you to be able to count on your dental restorations for many years to come!


Bridges are a great way to replace missing teeth. Dental bridges can be supported by your natural teeth or a dental implant.


Dental crowns can give severely damaged or decayed teeth a second chance at a long life. They look just like your natural teeth and can last a lifetime.

Full Mouth Restorations

Feeling proud about your smile is important – it’s also hard to feel proud about your smile when you’ve experienced significant tooth loss. For these reasons we offer full mouth restorations that give you a smile you have always wanted.

Cosmetic Dentistry


Veneers are a great way to alter your smile in just about any way you can imagine. We can fix spacing, size, and even shape issues with teeth that are featured prominently in your smile.

Teeth Whitening

Teeth whitening is one of the most popular cosmetic dental procedures that we offer because it produces stunning results fast!

Inlays and Onlays

Inlays and onlays are similar to fillings, but they are crafted in a dental laboratory and custom fitted to your tooth.

Dental Implants

Dental implants are currently the best tooth replacement option in the field of dentistry because they are permanent, restore health to your mouth, and work the same way your natural teeth do.

Sleep Apnea

Losing sleep is no fun and can be quite dangerous. Let us help to treat your sleep apnea!


If the dentist office makes you nervous, fear not – we offer dental sedation. Just ask us before your procedure and we will be happy to accommodate you!
