Frequently Asked Questions

How often should I visit the dentist?

For most people, we recommend a dental check-up and cleaning every six months. However, depending on your oral health conditions, we might suggest more frequent visits. Regular check-ups are crucial to prevent dental problems and maintain optimal oral health.

Is it necessary to take an X-ray during my visit?

Not always. We utilize X-rays to get a detailed view of areas not visible during a standard oral examination. This helps in diagnosing issues like cavities between teeth or problems below the gum line. While we don’t take X-rays at every visit, they are essential tools when evaluating and diagnosing dental conditions.

What should I do in case of a dental emergency?

If you experience a dental emergency, such as severe pain, swelling, a broken tooth, or trauma to the mouth, please call our office immediately. We prioritize emergencies and will do our best to see you as soon as possible. If the emergency occurs outside of our operating hours, please seek immediate medical attention or visit the nearest emergency room.

Why are regular dental check-ups important?

Regular check-ups help in the early detection and treatment of oral health issues, preventing them from becoming severe. They also ensure that your teeth are cleaned professionally, reducing the risk of cavities and gum disease.

How can I maintain good oral health between check-ups?

Regular brushing (twice daily), flossing (once daily), using an antiseptic mouthwash, and maintaining a balanced diet are vital for good oral health. Additionally, avoiding excessive sugary foods and drinks can help prevent cavities.
