Teeth Whitening in North Andover

Your teeth have turned yellow lately and you can’t find a whitening gel that works? You’re not alone. Many people struggle with stubborn stains that simply don’t respond to over-the-counter whitening products. At Osgood Cosmetic & Family Dentistry in North Andover, MA, we’ve cracked the code for whitening and we guarantee our results with the KöR Whitening System, one of the most advanced and effective whitening solutions available today.

Why Over-the-Counter Whitening Gels Often Fail

If you’ve tried whitening pens, strips, or store-bought gels without success, the problem isn’t you: it’s the product. Most whitening systems rely on carbamide peroxide or hydrogen peroxide, which release oxygen to lift stains from the enamel. However, these over-the-counter options fail for a few key reasons:

1. Inactive Gel: The whitening agent breaks down over time. Even if the product hasn’t expired, it may have been stored improperly or sat on a shelf too long.
   
   
2. Poor Tooth Contact: Pens and strips don’t fit securely, so the gel doesn’t stay in contact with the enamel long enough to work.
   
   
3. Dilution by Saliva: Without custom trays, saliva mixes with the whitening gel and dilutes its strength, making it ineffective.

At Osgood Cosmetic & Family Dentistry, we use the KöR Whitening System, which eliminates these issues entirely. The whitening gel is kept refrigerated from the time it’s manufactured until the moment it’s applied, preserving its full potency and ensuring consistent, beautiful results.

The KöR Whitening Difference

KöR Whitening is considered the gold standard in professional whitening because it goes beyond surface stains. It restores your teeth’s ability to absorb oxygen, allowing the whitening agents to deeply dissolve even the most stubborn discoloration.

Benefits of KöR Whitening at Osgood Dentistry:

• Noticeably whiter results in a single visit
  
  
• Safe and gentle on teeth and gums
  
  
• Minimal to no sensitivity
  
  
• Effective for tetracycline and deep-set stains
  
  
• Long-lasting results with easy maintenance
  
  
• Perfect for patients of all ages

In-Office KöR Whitening

For patients who want instant, dramatic results, our in-office KöR treatment can make your smile several shades whiter in just one visit. During your appointment, Dr. Gharib and our team apply a professional-strength whitening gel that activates on contact, lifting years of discoloration in as little as 60–90 minutes.

Whether you’re preparing for a wedding, interview, or special event, KöR in-office whitening provides the fastest and most effective results available in North Andover.

Take-Home KöR Whitening Trays

If you prefer to whiten at home, we also offer custom-fitted KöR take-home trays. After creating molds of your teeth, we fabricate precision trays that keep the whitening gel sealed tightly against your enamel for maximum effectiveness.

Patients typically wear the trays overnight for about two weeks. You’ll enjoy the convenience of whitening on your own schedule, plus the flexibility to use your trays later for easy touch-ups and maintenance.

Maintaining Your Whitened Smile

To keep your teeth bright and healthy after treatment:

• Avoid dark beverages (coffee, red wine, tea) for 48 hours after whitening
  
  
• Rinse or brush soon after consuming stain-causing foods
  
  
• Use a whitening-safe, non-abrasive toothpaste
  
  
• Schedule regular dental cleanings and exams
