Derry Dentists Providing Trusted Answers

Our team knows that when it comes to visiting the dentist, you have a lot of questions and concerns. 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 worries about visits to the dentist. Most often, there are two types of sedation: nitrous oxide gas or prescribed sedative pill. With nitrous oxide, you can 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 caused by a number of factors, including jaw-growth issues, overcrowded teeth, and 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 many myths about the best dental practices for children. The most prominent one is 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 when their first tooth appears is recommended. Another common misconception is that baby teeth don’t need to be treated. Untreated tooth decay or damage can affect the overall health of your mouth in the future.

Why Do Baby Teeth Need to Be Filled?

While baby teeth are temporary, they are still needed to help properly chew food and guide 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 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 look for improper growth or development, periodically re-evaluating your child’s needs, so if any issues appear we quickly and efficently create a treatment plan.

What Should I Do Before & After my Dental Visit?

Our team at Haas Dental Associates wants you to feel comfortable heading into your appointment which is why we’ve provided easy-to-follow guides for both before your visit and after your appointment.
