Frequently Asked Questions

  • Do you accept insurance?

    Yes, we accept most insurance plans. Call us to verify your coverage.

  • Can I get a crown in one visit?

    Yes, we offer same-day crowns using advanced technology.

  • Is Botox safe for TMJ treatment?

    Yes, Botox is a safe and effective option for reducing jaw tension and pain.

  • Are clear aligners better than braces?

    Clear aligners are a discreet and comfortable alternative to traditional braces.

  • Why choose a local dentist in Rochester Hills?

    Choosing a local dentist provides convenient access to routine care, emergency appointments, and long-term relationships with a trusted dental team close to home.

  • What areas do you serve?

    O'Brien Dental Center proudly serves patients from Rochester Hills, Rochester, Oakland Township, Auburn Hills, Troy, Shelby Township, Lake Orion, Washington Township, and throughout Oakland and Macomb Counties.

  • What is the difference between a dental crown and a filling?

    A dental filling is used to repair small areas of tooth decay or minor damage by filling the affected portion of the tooth. A dental crown covers the entire tooth and is recommended when a tooth has extensive decay, a large fracture, or has undergone a root canal. Crowns provide added strength, protection, and a natural-looking appearance.

  • Can a cavity heal on its own?

    Once a cavity has formed, it cannot heal on its own. Early-stage enamel demineralization may be reversed with fluoride treatments and good oral hygiene, but a true cavity requires professional treatment to prevent further decay and protect the tooth.

  • How long do porcelain crowns last?

    With proper care, porcelain crowns typically last 10 to 15 years, and many last even longer. Brushing, flossing, regular dental checkups, and avoiding habits like chewing ice or grinding your teeth can help extend the life of your crown.

  • Why are my teeth sensitive to cold?

    Tooth sensitivity can be caused by worn enamel, gum recession, cavities, cracked teeth, or exposed tooth roots. A dental examination can identify the cause and determine the most effective treatment to relieve discomfort.

  • What causes bad breath even after brushing?

    Persistent bad breath may be caused by bacteria on the tongue, gum disease, tooth decay, dry mouth, certain medications, or underlying health conditions. Regular dental cleanings and exams can help identify and treat the source of chronic bad breath.

  • How can I improve my smile without braces?

    Many cosmetic dental treatments can enhance your smile without orthodontics. Professional teeth whitening, porcelain veneers, cosmetic bonding, and tooth-colored restorations can improve the appearance of stained, chipped, uneven, or worn teeth.

  • What is the best age for a child's first dental visit?

    The American Dental Association recommends that children visit the dentist by their first birthday or within six months after their first tooth erupts. Early dental visits help establish healthy habits and allow for early detection of potential concerns.

  • Is it normal for gums to bleed when flossing?

    Healthy gums should not bleed regularly. Bleeding while brushing or flossing may be an early sign of gingivitis or gum disease. Scheduling a dental evaluation can help prevent more serious periodontal issues.

  • How long does a professional teeth whitening treatment take?

    Most in-office professional whitening treatments take about 60 to 90 minutes and can brighten teeth several shades in a single visit. Take-home whitening kits provided by your dentist are another effective option for gradual whitening.

  • What happens if I delay treating a cracked tooth?

    Delaying treatment for a cracked tooth can allow the damage to worsen, increasing the risk of infection, severe pain, or tooth loss. Early treatment often allows for more conservative and cost-effective solutions, such as bonding or a dental crown.

  • Do you offer preventive dental care?

    Yes! Preventive services include dental cleanings, exams, fluoride treatments, sealants, oral cancer screenings, and patient education to help prevent cavities and gum disease.

  • Does O’Brien Dental Center treat children?

    Yes! We provide gentle dental care for children and families, helping patients establish healthy oral habits from an early age. In addition, the Kids will love our family-friendly waiting room!  Dr. O’Brien is also a parent of a young boy and understands the need for a family-friendly environment, especially at a Dentist office.  

  • Can my entire family schedule appointments together?

    Absolutely. We offer family scheduling whenever possible to make dental visits more convenient.

  • Does O’Brien Dental Center you use digital X-rays?

    Yes at our Rochester Hills, MI location, we use Digital X-rays that provide the most detailed images using significantly less radiation than traditional film X-rays and allow for faster diagnosis.

  • What technology does O'Brien Dental Center in Rochester Hills use?

    Our office utilizes modern dental technology, including digital imaging and advanced diagnostic tools, and  CEREC® same-day crowns to provide accurate, comfortable care.

  • What are the signs of gum disease?

    Common symptoms include bleeding gums, persistent bad breath, swollen gums, gum recession, and loose teeth. Early treatment can help prevent more serious complications.

  • How can I prevent cavities?

    Brushing twice daily, flossing every day, maintaining a healthy diet, and visiting your dentist regularly are the best ways to prevent cavities.
