Totally Free Whitening is what separates North Garland Dental, Implants & Orthodontics from all other dentists. If you have PPO insurance, we will whiten your teeth for free. No exams, x-rays or cleaning involved. Just white teeth. Free. You can become at least seven shades whiter in about a week using them just 30 minutes a day. Just because our whitening is free doesn’t make it low quality. Dental trays with whitening gel are the safest, most effective, pain-free method of teeth whitening today. Our whitening gel comes in various strengths so you can choose the one right for you. And again, it’s totally free.
