“I broke my front teeth on Christmas day. I had an old bridge, and it just came out – on the Christmas morning! I had been Dr. Polevoy’s patient when I lived in Westchester, but I had since moved to Manhattan. I had no one else to call – and I had a huge party to go to that evening! When Dr. Polevoy heard what happened, he came in – on Christmas – and took care of my smile. It was the most amazing dental experience. I came in with 2 front teeth missing, and came out looking like nothing had happened. I am forever grateful to Dr. Polevoy for saving Christmas for me that year” – Susan L., Harrison.

Help! I Broke My Tooth!

Broken Tooth! What to do!

Almost every day we get a call from a patient who has broken a tooth, and generally it means that to save the tooth, we have to place a crown or permanent restoration over it to keep it from breaking further. Sometimes the tooth can’t be saved and that is a real bummer!

What causes teeth to break? Well, there are several factors, one of which we see in almost all tooth fractures. The most common contributing factor is Silver amalgam fillings- these fillings have the unique property of enlarging as they age. So, there seems to be some outward pressure on the tooth and if someone bites just the right (or wrong) way, you hear that crack!

Now this tooth broke in several planes at once, and had to be removed; there wasn’t enough sound tooth structure to save it! So an implant or bridge needed to be done.

This is a more common sort of fracture. The inside aspect of the tooth just shears away. Luckily, this tooth can be saved with a crown, after first making sure there is no decay present.

The second common factor is bruxism- the habit of grinding or clenching the teeth. Many bruxers break teeth that don’t even have fillings in them, but they always have a higher percentage of broken teeth than people who don’t brux or clench.

If you or someone you know does grind their teeth and are worried about a tooth or some teeth, don’t hesitate to give us a call and we will be glad to check it out for you! Don’t wait until it hurts!

Help! My child

Help! My child just knocked out a tooth!

An avulsed tooth is a common traumatic injury in kids.
In any dental trauma situation, the most important first step is making sure your child does not have a serious head injury.
Look for loss of consciousness, nausea, unsteady gait, disturbed vision, and confusion. If one or more of these signs is present, take your child to an Emergency Room immediately for a complete evaluation; the dental injury is a far lower priority.
Once head injury is ruled out, it is time to evaluate dental damage. Wipe your child’s mouth with a clean cloth to assess the damage. Call us at (914) 630-2833 – we will be able to guide you from there.
If the tooth knocked out was a baby tooth, very frequently, nothing needs to be done. Baby teeth do not need to be re-implanted – doing so can cause damage to the permanent tooth under it. We will evaluate the gum around it, making sure there was no damage to the bone.
An adult tooth needs a different approach. Find the tooth first. Gently rinse the debris off – DO NOT SCRUB. Place the tooth in a cup of liquid – saline is best, milk is the most common and effective substitute. CALL US IMMEDIATELY! If done quickly, we can often re-implant the tooth.

We understand that this is a traumatic time for you.
Wherever you are in Westchester; Harrison, Larchmont, Mamaroneck, White Plains, Rye and New Rochelle, we want you to know that our help is only minutes away.

What to do in case of dental emergency

Dental emergency can come in many forms.

Some are truly life-threatening.

Others are very painful.

And some are just very, very inconvenient.




True life-threatening dental emergencies are rare.  The common one is a swelling due to a nerve infection.

The reason this constitutes a true emergency is because mouth or cheek swelling can travel very quickly.   It doesn’t take much for the infection to begin to threaten the airway, making it difficult to breathe, or to travel to the brain, possibly causing brain damage.  Swelling is the most serious emergency we deal with, and must be addressed immediately.

If you have any of these signs:

  • swelling you can feel from outside the cheek
  • any new mass under your tongue
  • fever or chills after a recent dental treatment

contact your regular or emergency dentist immediately.  Some hospitals have emergency dentists on call or may have emergency dental clinics.  Please call the right away.

If you feel any swelling in the floor of your mouth or under your eye, you may want to head straight to the ER!


Although much rarer, bleeding is another life-threatening emergency.  Typically, it is a complication of dental surgery when the patient is taking blood thinners.  A patient on blood thinners, such as coumadin, warfarin, or even asprin is much more likely to bleed profusely.  Usually this is known in advance, and steps are taken to make sure the patient can stop bleeding in a reasonable time.

If you are still bleeding after a dental surgery, you can see the instructions we give to our patients after they have extractions or surgery done at our Westchester dentist office.

  • if you were given gauze by the dentist, apply heavy pressure to the extraction site for several hours
  • if the gauze still gets soaked after 2 hours, contact your dentist
  • if you are unable to reach your dentist, place a moistened tea bag on the extraction site and see if that stops the bleeding,
  • if you are still unable to stop the bleeding, please go the ER immediately.


The most familiar dental emergency is a toothache.

A dentist will try to determine the cause for the toothache by asking question about what causes it.

  • Does it last or go away right away?
  • Does it hurt to chew?
  • Does it hurt to tap?
  • Does it hurt to hot or cold?

Your answers will guide the dentist to find out what’s causing it.

For instance, a toothache that is caused by very cold liquids or foods, doesn’t linger, never begins if you’re not doing anything, never wakes you up at night – is typically tooth sensitivity caused by something being exposed – a root surface because of gum recession, a cracked filling, a loose crown.  It is usually not likely to get much worse, and treatment for it is relatively simple.  Sometimes it’s as easy as applying a fluoride paste to the sensitive teeth, or replacing or repairing the filling or crown.

If the tooth is sensitive to HEAT, THROBS constantly, or wakes you up at night, the cause is most likely a nerve abscess.  Nerve abscess means that the nerve inside the tooth is infected, and needs to be removed.  Two ways of taking care of it are a root canal or an extraction.

Dealing with dental pain

While you are waiting to see the dentist for definitive treatment, you may need to deal with dental pain.  Unless your dentist or physician recommended something else, we suggest using over the  counter painkillers to help.  Motrin, Advil, or Alleve are all excellent painkillers that can deal with mild to moderate pain levels.  For an added pain control, you may want to consider adding one tablet of Tylenol.  Advil/Tylenol combo is usually safe and effective painkiller FOR MOST PATIENTS (CONTACT YOUR DENTIST OR PHYSICIAN FOR ADVICE SPECIFIC TO YOUR SITUATION)

Loose Crowns

Dental crowns can get loose and come off of the tooth.  Whether or not it constitutes an emergency depends on several factors.

  • Is there dental pain/toothache?
  • Is the tooth root canaled?
  • Is it a front tooth?

Typically, if a crown comes off, you do not need to worry about the exposed tooth getting infected in a couple of days.  The tooth underneath is sealed, and will be fine for a day or two until you can see your dentist.  But don’t wait longer than that!   Teeth can shift very quickly, and the crown may no longer fit.  Waiting for more than a few days raises the chances your dentist may not be able to just glue it back in.

If the tooth is very sensitive, or is a very visible, you may want to try to put the crown back on yourself in the short term.  While many pharmacies sell temporary cements, they are not very user-friendly.  You may have a better luck with denture adhesive such as Fixodent.

Avulsed (Knocked Out ) Teeth

This typically happens with kids and adolescents.

If the knocked out tooth was a baby tooth, no treatment is typically needed.  We rarely place the baby teeth back in, because the prognosis is very poor.

More often, it is an adult tooth that gets knocked out.  If that happens, the tooth needs to be reimplanted.  There is an excellent step-by-step guide here.
