We Protect Smiles with Preventive Dentistry

Our dental team is here to treat any oral health problems you and your loved ones experience, but our preference would be to help you avoid them in the first place. With quality preventive dentistry, Dr. Hien Nguyen is able to strengthen smiles, guard against decay, and correct common ailments early before they have the chance to develop into more dangerous conditions that could wreak havoc on your smile. Contact Smile Design Dental here in Plano, TX today to schedule your first checkup and cleaning!

Dental Sealants

There are certain areas of your teeth that can be magnets for tooth decay, especially the deep chewing grooves in the premolars and molars towards the back of the mouth. What’s worse is that these areas can be tricky to keep clean with routine oral hygiene, especially for children who are still learning how to brush and floss properly. Thankfully, Dr. Nguyen offers a helpful preventive solution – dental sealants.

Dental sealants are a safe, comfortable, and quick treatment that can provide valuable protection for several years. This high-quality plastic material is applied directly to the chewing surfaces of certain teeth, creating a barrier that keeps food particles and dangerous bacteria at bay. While we typically recommend sealants for younger patients, adults who struggle with tooth enamel that’s overly sensitive to decay may benefit as well.

Nightguards for Bruxism

If you struggle with worn tooth enamel, severe headaches, or lingering facial/jaw discomfort on a routine basis, it’s possible you’re experiencing bruxism (teeth grinding). This “bad habit” is common among adults who experience routine daily stress, but it can affect patients at all stages of life – and what’s worse is that the grinding typically occurs during sleep, making it virtually impossible to stop alone. Without intervention, bruxism can lead to significant dental damage and the development of TMJ disorder, which can cause severe, even debilitating pain.

At Smile Design Dental, patients can turn to Dr. Nguyen for the effective bruxism treatment they need. Our team can design the ideal oral appliance (also known as a “nightguard”) for your mouth, providing a stable barrier between teeth that reduces the severity of teeth grinding. 


You only have one smile, and keeping it safe is important! This is especially true when you’re playing your favorite sport out on the field or court – the possibility of physical contact with other players or hard surfaces can spell trouble for vulnerable teeth. Here in Plano, our team strongly recommends that patients from Plano, TX and surrounding areas invest in a custom-made sportsguard from Dr. Nguyen. Unlike the lackluster appliances you could pick up at the store, our designs are comfortable, flexible, and sturdy for quality protection.

Oral Cancer Screenings

Every year, tens of thousands of people are diagnosed with oral cancer, and nearly half of them won’t live more than five years past this point, according to various studies. This happens because most of these cases aren’t caught until they’ve already progressed to advanced stages, making recovery a difficult goal. At Smile Design Dental, we do our part to catch oral cancer as early as possible with diagnostic screenings. If Dr. Nguyen notices any abnormalities in your oral tissue that could suggest the presence of cancerous cells, he will recommend a biopsy for your safety.

Emergency Dentistry

If your or your loved one is experiencing a sudden dental injury or severe oral pain, don’t hesitate to reach out to our Plano, TX practice right away for the emergency guidance and treatment you need most. Dr. Nguyen offers extended hours in the evenings and on weekends, and emergency walk-ins are always welcomed. Common situations that should be considered urgent in nature include:

Children’s Dentistry

We love seeing whole families at Smile Design Dental, including the youngest members! Dr. Nguyen and the rest of our team have plenty of experience with helping children feel calm and at ease throughout their dental appointments, and we’ll be sure to personalize their care to match their current level of emotional maturity. Gentle check-ups will reveal any early signs of tooth decay, as well as developmental concerns that may need attention right away. As they grow older, we can also teach your son or daughter how to brush and floss properly. Best of all, our extended appointment times (including weekends) means that they won’t have to miss school to receive the dedicated attention their oral health needs!

Gum Disease Treatment

Gum disease (also known as periodontal disease) is one of the most common health conditions on the planet – in fact, some studies suggest that up to 80% of the population could be suffering from it, whether they know it or not. While gum disease is relatively mild in its earlier stages, untreated cases can eventually cause tooth loss and other severe damage to your oral health and overall wellbeing. That’s why early diagnosis and treatment is an absolute priority for Dr. Nguyen.

During your routine appointments, our Plano team will perform a thorough periodontal screening to determine whether infection is present. If treatment is needed, we offer an in-depth cleaning known as scaling and root planing that can remove dangerous plaque and bacteria from under the gum line and the tooth’s root surfaces.
