Hi there,

Yes, there is a genetic predisposition. Many people have retained baby teeth, a panoramic X-ray is taken to see if the succeeding adult tooth is present. If not, life goes on and if they loose the tooth you can replace with an implant ideally. If they require braces, the orthodontist will advise as needed. If the permanent tooth is present, but impacted, other modalities of treatment are available, i.e., braces with traction. For the time being, relax and enjoy the kids!

Are dental x-rays really safe?

Hi there, Dental X-rays exhibit much less radiation than many medical diagnostics, i.e., chest X-rays, etc. These days, a majority of dentists have incorporated digital X-rays READ MORE
Hi there,

Dental X-rays exhibit much less radiation than many medical diagnostics, i.e., chest X-rays, etc. These days, a majority of dentists have incorporated digital X-rays which require much less exposure time, hence even lower radiation. However, the ALARA principle (as low as reasonably achievable) is always followed. The normal individual will have X-rays every 18 months. If the individual has a high caries (cavities) incidence, the frequency is shorter to catch and treat when decay is minimal. Prevention is better than the cure!

Hello,

Periodontists are specialists in gum and the surrounding tissues. They have gone to school for an extra 3-4 years. Dentists generally can do all aspects of dentistry as long as they are proficient and comfortable in those procedures. There is no panacea to choosing one over the other. Your dentist will refer if required or you visit a periodontist if you are more comfortable for that procedure. Generally periodontist will do gum or bone grafts, implants, and gum therapies to maintain healthy periodontium, i.e., pocket elimination, root planing, flap surgeries, to name just a few.

Hi there,

Very interesting! I have used acupuncture to deal with a patient’s gag reflex. Alternative medicine is interesting, but not a panacea to deal with all dental pain. Perhaps if the pin is muscular, it may help, but if tooth-related, you will need to see a dentist.

Which is better, root canal or implant?

Hello
Interesting question. As health care providers we are to provide you with all the options and consequences allowing you to make the final informed decision. That being said, I personally feel if a tooth is given a fair to good prognosis I would try and keep it. However, if the prognosis is poor to guarded, and implant may make more sense. Root canals have been given a bad rap, but scientifically are sound and do work. Hope this helps.

Hello,

Yes, it’s a somewhat common fear. Some options to help your grandmother: the dentist can use a rubber dam or isolite system to help minimize the water in the mouth. If the anxiety borders fear, she may require sedation. The body has natural reflexes, which will obviously prevent choking. This is more a psychological issue, so reassurance is important. Have a consult with the dentist and hopefully he can create trust, showing care and empathy.
I wish your grandmother well. Hope this helps.

Hi there,

TMD is usually treated with a mouth guard. Different types are available and your dentist can determine what’s best for you. Botox can help if it is muscular in nature. Anti-inflammatory and warm compress helps in conjunction with mouth guard. The last resort is surgery and it is not always successful. I would recommend conservative treatment with a guard first.

Can I have orthodontic advice for class 3 malocclusion?

Hi,

Hope the move to LA went well!! Class III is a difficult task...the diagnosis is very important. As I am not an orthodontist, I can only give you my thoughts. Depending on the ceph analysis, we can determine what the growth pattern is for the child; if the child is a vertical growth pattern with an anterior open bite, it will be advisable to wait till after her growth spurt, as her continued growth will result in a failed orthodontic treatment, i.e., open bite reoccurs. Sometimes, regardless of interceptive attempts, jaw surgery may still be required. Another reason to possibly wait till after growth. Again, very difficult to assess without all the information. But do seek out a reputable orthodontist in your new neighborhood and ask all your questions.

Hope this helped.
