Derry Dentists Providing Trusted Answers

Our team knows that when it comes to visiting the dentist, you have a lot of questions and concerns—and we are here to help put your mind at ease. We are addressing some of our most frequently asked questions below, so you feel comfortable heading into your next appointment.

What Are the Benefits of Sedation Dentistry? And Is It Safe?

Sedation dentistry is a safe way to reduce the stress around visits to the dentist. Most often, there are two types of sedation, nitrous oxide gas or prescribed sedative pill. With nitrous oxide, you can even drive yourself to and from your appointment. Reach out to our team to learn more about which method is right for you.

What Is Orthodontics?

Orthodontic treatments are designed to realign your teeth, lips, and/or jaw. These problems can be due to any number of reasons, including jaw-growth issues, overcrowded teeth, or spacing problems—and can develop or worsen over time without treatment. We make your first Orthodontic appointment convenient—starting with a thorough evaluation to discuss all your potential treatment options.

What Are Some Common Myths about Children’s Teeth?

Starting proper dental habits early is the best way to ensure a healthy smile for life, however, there are tons of myths out there about the best dental practices for children. The most prominent one being that you don’t have to bring your children to the dentist until they start school. In reality, bringing your child in for a pediatric dentist appointment the moment their first tooth comes in is what is recommended. Another common misconception is that baby teeth don’t need to be treated, when in fact, untreated tooth decay or damage can affect the overall health of your mouth for years to come.

Why Do Baby Teeth Need to Be Filled?

While baby teeth are temporary, they are still needed to help properly chew food and guide the adult teeth into the proper position. This means baby teeth are crucial for setting up your mouth for success in the future.

What Is a Crossbite and Can I Get it Corrected?

A crossbite is a misalignment of the teeth. Whether caused by a larger jaw issue or an abnormal teeth eruption, a crossbite can wear down enamel and even lead to lopsided jaw growth. The good news is, depending on the severity, it can be fixed by orthodontic treatments, such as a palatal expander.

When Should Children Receive an Orthodontic Evaluation?

Not every child needs orthodontic treatment, but they should receive an evaluation by age 7. This early detection can accurately spot any problems that might be developing. We will watch for improper growth or development, periodically re-evaluating your child’s needs, so if any issues pop up we get a treatment plan in place fast.

What Should I Do Before & After my Dental Visit?
