Teeth Whitening Service – Cottage Grove MN

Your smile is important. It’s one of the first things you notice when you meet someone. A whiter, brighter smile is beautiful – it help you feel better about yourself and make a memorable impression.

Your lifestyle and the aging process can stain and darken your teeth. Many things we do on a regular basis can contribute to stained teeth, such as drinking coffee, tea, cola and red wine or smoking.

Whitening can get your smile looking its best. Non-professional procedures and clinically unproven teeth whitening tips can often lead to unsatisfactory results, you should look for a whitening procedure that is:

  • Fast and convenient
  • Long lasting
  • Low sensitivity
  • Proven to be safe and effective
  • Performed by a Dental Professional

We can whiten your teeth with a product called Zoom! Whitening, in 45 Minutes!


This is the procedure of making teeth whiter, and therefore more attractive. Our office uses several methods: Zoom!, passive tray whitening, and professional strength white strips.

Zoom! is a revolutionary tooth whitening procedure. It’s safe effective and fast, very fast. In just over an hour, your teeth will be dramatically whiter. The convenience of Zoom! in comparison to days of using strips or wearing trays makes it the perfect choice for the busy individual. The Zoom! Whitening procedure is simple.

It begins with a short preparation to isolate your lips and gums. The clinician then applies the proprietary Zoom! whitening gel that is activated by a specially designed light. Teeth typically become at least six to ten shades whiter, sometimes more.

A fluoride treatment completes the procedure. You’ll be amazed with the results. In most cases, teeth get even whiter the first few days after the procedure. Trays with gel are recommended afterward for maximum whitening and maintenance.

The tray method involves having impressions taken from which laboratory fabricated custom vinyl trays are made. A carbamide peroxide gel is placed in these trays and the trays with gel are worn for about 3 hours, or overnight. The entire process takes 3-4 weeks of daily use. Three different strengths of gel may be used, however the higher the strength the greater the likelihood of reactions or tooth sensitivity. The tray method is recommended for badly stained teeth, such as tetracycline staining, and it may take several months of use to see significant color improvement. For maintenance of whitened teeth the trays should be used every several months.

The end results whether using trays at home or doing Zoom! is the same. The cost of the tray method is about half compared to Zoom!, and there is usually less post-treatment sensitivity.

Biolase Dentist Cottage Grove, MN

BIOLASE® Technology designs innovative dental lasers to reduce the complexity and trauma associated with many common dental procedures. The “drill” strikes fear into the hearts of many with its noise, vibration and heat.

The Waterlase® device utilizes hydrokinetic technology to remove hard and soft tissue with laser-powered water droplets. There is no heat, no vibrations and no noise associated with the Waterlase laser, and it is completely safe. The FDA deemed the hydrokinetic laser safe for use on both adults and children in 1998.

The BIOLASE® Waterlase® is an extremely versatile piece of dental equipment. It can be used to either perform or expedite many procedures including:

  • Caries removal.
  • Cavity preparation.
  • Dentin and enamel procedures.
  • Gum reshaping.
  • Removal of decay.
  • Soft tissue procedures.
  • Treatment of cold sores

What benefits does BIOLASE® Waterlase® offer?

Waterlase® works by precisely combining atomized water and laser energy to gently remove hard and soft tissue. This precision laser means that in most cases, there is no need for anesthesia. Additionally, the laser actually sterilizes the surgical area, meaning that there is less risk of bacterial invasions or infections. For children and fearful patients, the Waterlase® offers a needleless, painless way to achieve the perfect smile.

Here are some reasons why using Waterlase® is preferable to the traditional dental drill:

  • Adjacent teeth remain unaffected.
  • Faster and stronger bonding of fillings.
  • Less of the healthy tooth is removed.
  • Minimal bleeding during and after procedures.
  • No noise, heat or unpleasant vibrations.
  • Pinpoint accuracy generates better results.
  • Reduced number of dental visits.

Botox Treatments Cottage Grove, MN

Dentistry by Kretchmer is pleased to be providing Botox Cosmetic as a simple, nonsurgical, physician administered treatment that can temporarily smooth moderate to severe frown lines between the brows in people from 18 to 65 years of age.

Botox Cosmetic® can significantly reduce the appearance of wrinkles on your face and can improve the following areas:

  • Worry lines in forehead
  • Lines between the eyebrows (glabellar)
  • Smile lines
  • Laugh lines
  • Crow’s feet
  • There are also treatment options for headaches and TMJ issues

At Dentistry by Kretchmer you will always see the doctor for your treatment -I believe Dentists are particularly well suited and trained to administer Botox in the facial muscles. Dentists receive extensive education in head and neck anatomy. This training and understanding of facial musculature and the effect it has on appearance and function is the foundation of understanding what effect a Botox injection will have on any given patient. Dr. Kretchmer has also received extensive additional training and is a member of the The American Academy of Facial Esthetics. Our technique is very gentle and an ice pack is always applied to the areas we will be working on. Small injections are administered directly into the area you would like to improve. Botox Cosmetic® goes to work immediately on the facial muscles that are causing wrinkles. You will begin to notice visible improvements over the next month.

***We are offering an introductory special on Botox $139.00 for up to 20 units.***

Derma Fillers (Juvederm XC)

Juvederm® is a smooth consistency gel made of hyaluronic acid, a naturally occurring substance in your skin that helps to add volume and hydration. Your doctor eases JUVEDERM® injectable gel under the skin to instantly restore your skin’s volume and smooth away facial wrinkles and folds, like your “smile lines” or “parentheses” (the creases that run from the bottom of your nose to the corners of your mouth).

JUVEDERM® provides a smooth, natural look and feel – so everyone will notice (but no one will know)! In fact, studies show superior results of JUVEDERM® compared to collagen- based dermal filler. JUVEDERM® injectable gel is the first FDA approved hyaluronic acid dermal filler that is proven to be safe and effective for persons of color.

With JUVEDERM® the injection process takes approximately 15 minutes and the results are immediate. Plus, there’s minimal recovery or downtime. So you can step into our office for treatment and step right outside and continue on with your day.
