“I have been going to Dr. Palmer for over 20 years. Even though I moved an hour away I still go to her. Why? Because I trust her. She is the ultimate professional that truly cares. Along with Cathy, dental hygienist and Jennifer, office manager, I always feel like I am in good hands. Without a doubt I highly recommend Dr. Palmer.”

Jane B., Mission Viejo, CA

“If you or someone you know doesn't like going to the dentist - go see Dr. Palmer. You will feel comfortable each time and you will enjoy a healthy mouth for life. And, don't be embarrassed if you haven't been to the dentist in a while. And don't be scared if you or your children don't like dentists. You are in expert, safe, and caring hands with Dr. Palmer and her people.”

“Dr. Palmer and her team are awesome! I am sought her out for Invisalign treatment and it has been amazing. The scans were painless and efficient. The aligners were changed out weekly and even during COVID were delivered to my home! Dr. Palmer and her team are excellent and should be your choice for Dentistry.”

Frequently Asked Questions

Palm Dentistry is no stranger when it comes to questions regarding all sorts of dentistry. Dr. Palmer encourages patients to learn as much as possible about their oral health as well as the services we complete to protect it for many years to come. If you’re just learning about our practice for the first time, feel free to review a handful of the most common questions we hear ahead of your very first appointment!

How do I find a female dentist?

More and more women are entering the dental field these days, including the role of dentist! In fact, it’s estimated that about one-third of dentists currently working in the U.S. are women. Interestingly enough, more than 50% of all, current dental school students are female as well. When you want to have a female dentist specifically, it always helps to check Google first as well as keep your search within an area you’re willing to travel to regularly. Not only are both of Palm Dentistry’s dentists women, but so are all of our team members!

How can I make a same-day appointment with a dentist?

We recommend that you call our practice directly in order to increase your odds of getting a same-day appointment, especially earlier in the workday. Sending an email is generally not the best way to get the quickest response as we may not get to it in time. When you call, you’ll also get to speak with a team member directly. They can then take note of your dental concerns or symptoms and try to work you into our schedule as quickly as possible. Our main goal with same-day appointments is to evaluate your condition, remove any problems (such as pain) before you leave, and get you on a dedicated treatment plan.

How do I get emergency dental care?

Always call our practice directly when you have a dental emergency. However, if you believe your urgent issue is life-threatening, we recommend dialing 911 or going to the emergency room first. After you’ve stabilized, make a visit to our office so we can more closely evaluate your dental issue. If your dental symptoms are not life-threatening, we recommend coming to our office first as most emergency rooms are not equipped to handle dental emergencies. Don’t put off a visit to our practice as dental emergencies are generally an indication of a bigger problem, such as tooth decay, gum disease, or an oral infection.

What is the best way to find a cosmetic dentist?

Since there is no single designation for a cosmetic dentist, that means any dentist can technically call themselves one of they want to. This is why it’s important to look for other indicators that show their expertise within the field of cosmetic dentistry. This could include written testimonials or reviews from patients that have received cosmetic treatments. Palm Dentistry is happy to offer multiple services that you may not find in your typical dental office, including gum recontouring, Lumineers, and multiple teeth whitening options.
