  • Dr Cook and his staff are amazing!

    I have always had a fear of dentists and because of that, I would never go to an Orthodontist. After watching all 3 of my children go thru the process and have beautiful teeth, I decided to give it a try. I have always been self conscience about my teeth and finally, at age 41 decided to do something about it. I wouldn't go to anyone else. Dr Cook and his staff are amazing. They make sure I am doing ok, they always tell me what they are about to do before they do it. They make me very calm and I feel comfortable. If you think you can't afford braces, then this is definitely the place for you!! They work with you by allowing affordable payment plans. Not to mention, family discount! If you have always wanted that beautiful smile, for either your children or yourself (no matter your age), Cook Orthodontist is for you!! Give them a try, what do you have to lose but a great smile!

Great smile = confidence

Research shows that the better you feel about your looks, the better you feel about yourself. When your teeth look white and sparkly, you can relax, be in the moment and laugh. You are more confident and radiant. The mere act of putting your mouth in the shape of a smile changes the blood flow to the brain and actually makes you feel happier. The fact that smiling itself boosts your mood has a further positive impact because smiling has a contagious effect. When you smile, others are more likely to smile back, and are more drawn to you, thereby increasing your confidence and happiness even more.

Smiles and perception

You might not realize it but whether or not you’re smiling can have a significant impact how others perceive you. Having a radiant smile sends a huge positive message to those around you. It tells people that you are happy to be in their presence, and it creates an optimistic feeling in others. When you smile, people are more likely to assume you have positive qualities — they perceive you as more sociable, trustworthy and intelligent, compared to when you aren’t smiling. So whether you’re at a party, in a job interview or simply walking down the street, the fact that you’re smiling will work to your advantage.

Being unhappy with your smile usually means you don’t do it very often – which means you aren’t reaping the benefits outlined above. People who avoid smiling usually do so because they are unhappy with the appearance of their teeth. When this happens people fall out of the habit of smiling or they do a closed-lip grin, which comes across as awkward or not genuine.
