If you want whiter teeth, try to avoid eating or drinking anything that could harm your efforts. You don't want all your efforts to be in vain because you stick with the same bad habits. Make a conscious change in your lifestyle to maintain your bright smile.
Ask your friends and family that you know nearby what dentist that they recommend. Word of mouth feedback and personal experiences are often the best indicator of the quality of work you can expect from local dentists. Check online reviews and community focused forums as well for other's experiences.
Know that some people are more prone to tarter build up than others, and not addressing this issue can be costly to your teeth. If you've learned you have a problem with tarter, invest in a specialty toothpaste and follow it up with detailed flossing and an anti-tarter mouth wash. The effort will pay off.
