Dental FAQs

Get all your burning questions about dental care answered! Our expert dentists provide clear and concise explanations on common concerns, from oral hygiene tips to understanding dental procedures. Discover the key to a healthy and confident smile.

Should I update my manual toothbrush to an electric?

When used appropriately, a manual toothbrush is as effective as a powered toothbrush. The key is to brush for the recommended two to three minutes, using short strokes at a 45-degree angle to the gums, and covering the entire tooth surface – inner, outer, and chewing.

How can I protect my teeth from damage?

The enamel on our teeth is hard, but as we all know, it can be chipped and cracked. In addition to following the instructions of your hygienist, here are some other ways you can protect your teeth:

My morning doesn't start until I've had my first cup of tea. How bad is this for my teeth?

Tea and coffee are safe to drink in moderation. However, over time, large amounts can cause staining and damage. In addition to caffeine, tea and coffee contain chromogens, deeply pigmented molecules that adhere to dental enamel, and tannins, which boost a chromogen molecule’s ability to attach to dental enamel. Black tea is worse than black coffee, because coffee is lower in tannins.

Are dental X-rays safe?

Yes. New digital X-ray machines limit the low-dose radiation to a beam that targets only the areas needed to be filmed, faster film speeds allow for shorter exposure times, and the use of film holders prevents slipping, reducing the need for repeated exposure due to retakes. Stray radiation is almost non-existent with the use of modern dental X-ray machines, but the use of lead-lined, full-body aprons protect against even that possibility. Every two years, federal law requires X-ray machines to be checked for safety and accuracy, and some states have even more stringent regulations.

I'm pregnant. Is it safe for me to go to the dentist?

Congratulations! Yes, you should continue to see your dentist, as pregnancy can increase certain dental issues. Be sure to inform your dentist that you are pregnant and if you’re experiencing any changes in your oral health.

Why don't my dentures fit right anymore?

The tissues and bones of your mouth may shrink (atrophy) with the passage of time or with the gain or loss of body weight, causing a change in the fit of your dentures. A simple realign may help them fit snugly again. However, if you’ve worn your dentures for a number of years, or the bases are too far out of shape, it may be time for replacements. It is counterproductive to use more denture adhesive to try to make them hold better, because this may lead to faster bone loss and additional problems with the fit of your dentures.

I've heard that my silver-colored fillings contain mercury. Should I have them replaced?

Dental amalgam (silver) fillings comprise silver, tin, copper, and liquid mercury, which are combined to form an inert (non-active) alloy. According to the FDA, CDC, the American Dental Association (ADA), and a number of other public health agencies, there is no link between this type of filling and any known health issue. Because of speculation and controversy, amalgam is the most researched and tested dental filling material on the market.

Our Patient Say the Nicest Things

Here’s what our happy patients say about us.

S M

I have been a patient of Dr. John HA for couple years now, and undergoing dental treatment in the pass has always been a unpleasant experience for me. This is mainly because I have often found myself on the receiving end of doctors’ conversations, where they would inform me that I need surgery to fix my teeth, but in a way that made me feel belittled and ashamed. However, after finally deciding to get dental implants, I chose to go with Dr. HA after reading positive reviews. I approached this decision with the mindset that if I felt judged or criticized about the condition of my teeth, I would seek treatment elsewhere. From my very first consultation to the permanent implantation of my implants, Dr. HA and his staff have truly made this surgery the best decision of my life. For nearly two years, I have been traveling from the Big Island to Oahu to receive my treatments. I understood that if I wanted to regain a sense of normalcy, and be able to eat and smile confidently, I had to trust that the staff would make the right decisions and guide me in the correct direction, as I had no knowledge of the process. The front office staff were incredibly helpful and accommodating, always being flexible with scheduling and accommodating my family when necessary. The dental assistants made me feel like a friend rather than just a customer, and Dr. HA himself took the time to explain the entire operation process from start to finish. He also discussed additional measures to ensure that I felt confident in achieving the results I desired. I cannot express enough gratitude to Dr. HA and his staff for their invaluable assistance throughout my procedures. Best dental establishment hands down!!.

Dr John Ha and his team were amazing. I’m from California and had a dental emergency in Waikiki. I contacted his office and they made time to see me. I only spent an hour and a half there and they did amazing. Allowed me to continue with my vacation with some peace of mind. Thank you so much.

From stepping into the office, it and the staff were very welcoming. Had an 11am appointment and there was no waiting. At 11, they were calling me in. Karen was very nice and professional taking pictures. During the exam, I suddenly felt very “out of sorts” and had to leave to get some air. Shawn came out to make sure I was OK and was very caring and we appreciated her kindness and understanding. Mahalo HSD!

There is no better dentist. I have never been to this location, but saw him at a previous practice. Dr. Ha is the perfect dentist. I had severe dental anxiety which caused me to neglect my teeth health, needed a root canal. He made me stop hating the dentist. He is caring, funny, has amazing banter and is just genuinely an awesome dude. Since he moved practices I’ve had no one that can possibly compare to him. Do yourself a favor and choose him for your dental care. I wish I still could.
