The Big Impact of What You Do Before Your Appointment

You might not know it, but what you do a few hours before your dentist visit matters—a lot. Imagine this: you eat garlic bread, drink a big mug of coffee, and then brush your teeth too hard until your gums bleed. Soon, you’re sitting in the dentist’s office, and things just don’t feel right.

Your dentist and hygienist depend on what they see and smell in your mouth. Strong foods, brushing too hard, or some medicine can fool your dentist. Even your mood or if you’re drinking enough water makes a difference. Getting ready for your appointment isn’t just being polite—it helps you have an easier, better visit.

Foods and Drinks to Skip

1. Stay Away from Smelly Foods

Garlic pasta, onion bagels, spicy food—they can be tasty, but you should wait until after your dental appointment. Why?

Covers Up Problems: Strong smells can hide bad breath that might mean you have infection or gum problems. Your dentist needs to know what your breath is really like.
Not Nice for Your Dentist: Strong smells can stay, making your dentist’s or hygienist’s job less pleasant.

2. Don’t Eat Sweets and Sour Drinks Right Before

Candy, soda, or fruit juice just before your visit? It’s not a good idea.

Sticky Mouth Stuff: Sugar and acid can make more plaque, which can fool your dentist into thinking your teeth are in worse shape.
Tricky Sensitivity: Sugar can make teeth feel extra sensitive for a little while, making it easier for your dentist to get the wrong idea.

3. Coffee, Energy Drinks, and Caffeine—Be Careful

Love coffee? You’re not alone! But maybe skip that cup right before your dentist visit.

Makes You Jumpy: Caffeine can make you more nervous if you already get worried about the dentist. It can also make your blood pressure go up, making sedation harder.
Dries Out Your Mouth: Caffeine can dry out your mouth, which can make it harder to check your gums.
Makes Your Teeth Look Stained: Coffee stains teeth, and fresh stains might make it harder for your dentist to check your real tooth color.

4. Don’t Drink Alcohol Before

A little drink the night before might help you relax, but don’t drink alcohol before your appointment.

Dries You Out: Alcohol drys out your mouth, which makes cleanings less comfy.
Problems With Sedation: Alcohol and anesthesia don’t go well together, which can make the effects last longer or make things riskier.

In Short: Save smelly foods, sweets, and drinks for after your visit. Your dentist—and teeth—will thank you.

Medicine, Other Substances & What to Tell Your Dentist

1. Watch Out for Blood Thinners & Pain Medications

Taking aspirin or ibuprofen before your visit for a small ache? Not always a good plan, especially if you’re having a cleaning, tooth pulled, or anything else.

Makes You Bleed More: Medicines like aspirin, ibuprofen and other painkillers can thin your blood and make you bleed more during gum work or taking out a tooth.
Ask First: Don’t stop taking anyone’s prescription without asking. But always tell your dentist about what you take.

2. Don’t Smoke or Vape

You might want a smoke to calm down, but smoking is not a good idea before your visit.

Slows Down Blood Flow: Smoking or vaping makes your blood move slower in your gums, which means slower healing.
Smell and Other Problems: Smoke and vape stick around and can hide things your dentist needs to see.

3. Don’t Use Cannabis or Street Drugs

Some people think a little cannabis helps with nerves. In reality, skip it.

Problems With Anesthesia: Some drugs can change how you respond to numbing or sleep medicine, making dental work less safe.
Feels Weird: Drugs can make you feel pain differently—which means your dentist may have a harder time keeping you comfortable.

4. Tell the Truth About All Medicine

Maybe you started a new vitamin, have antibiotics, or take regular meds for your heart or blood pressure. Always tell your whole health story.

Weird Reactions: Some drugs mix badly with numbing medicine or affect bleeding.
Stay Safe: Telling the truth keeps you safe.

Good Tip: Bring a list if you’re not sure! Your dentist’s job is to help, not judge.

Good Hygiene and What NOT to Do With Your Appearance

1. Don’t Skip Brushing or Flossing (But Don’t Go Crazy)

You might want to “fix” your smile by brushing and flossing extra hard before your visit. Don’t!

Irritated Gums: Scrubbing too much can make your gums sore and bleed, which makes it harder for your dentist to see if there are real problems.
Coverson Up Problems: Too much mouthwash, especially the kind with alcohol, can cover up breath problems from real dental issues. Alcohol also dries out your mouth more.

The Best Way: Just brush and floss like usual—don’t do anything out of the ordinary.

2. Skip Heavy Makeup and Lipstick

Makeup, especially near your mouth, gets in the way.

Gets Messy: Lipstick can get on your bib, gloves, and dental tools.
Blocks the View: Thick face makeup can make it harder for your dentist to see or take pictures.

3. No Gum or Strong Breath Fresheners

Popping in a gum or using breath spray before your visit seems polite, but don’t.

Covers Problems: Minty gum or sprays can hide signs of dental issues your dentist needs to know about.
Irritating Stuff: A lot of gums and sprays have alcohol or sugar, which isn’t good for gums or teeth.

4. About Contacts and Jewelry

Contacts are fine most of the time, but for really long appointments or if you’re being put to sleep, you may need to take them out. Check with the office first.

Dress Tips:

Wear comfy clothes.
Don’t use perfume—some people are allergic or sensitive.
Wear something easy to clean.

Getting Your Mind and Details Right

1. Don’t Let Your Worries Take Over

Lots of people get nervous about the dentist—if you’re anxious, that’s normal. If you let it get out of control, you might end up more sore or stressed.

What Helps?

Speak Up: Tell your dentist or the staff if you’re scared—they care and want to help.
Bring Comfort: A small object, headphones, or a friend in the waiting room can help you relax.
Breathe In, Breathe Out: Deep breathing can calm your nerves.

2. Don’t Be Late (or Miss Your Appointment!)

It’s easy to run late, but get to your appointment 10-15 minutes early if you can.

Respect for Time: Being late may cut your appointment short or even get it canceled.
Paperwork and Time: Getting there early lets you update your health info or ask questions.

3. Don’t Hide Important Info

Trying to just “deal with it” or skipping info about your health is a dangerous mistake.

New Allergies or Changes: Always tell them about new medicines, allergies, pregnancy, diabetes, or heart problems.

Remember: Your dentist is your teammate, not there to judge you.

4. Don’t Trust Everything You Read Online

It’s easy to get dental advice from the internet, but your dentist relies on what they see and know—not what you read.

Don’t Try Tricks: DIY “fixes” can’t replace professional help.
Ask Your Dentist: If you have questions, just ask! They’re the experts.

Quick List: What You Should Do Before Going to the Dentist

Now, let’s flip things and highlight what you should do:

Brush teeth and floss as normal.
Drink enough water. A wet mouth is best for your check-up.
Eat a small, healthy meal if you won’t be sedated. Low blood sugar makes you feel bad.
Arrive early, calm, and ready.
Bring a list of your medicines and any health changes.
Ask questions!
Drink less caffeine, and don’t smoke or vape before.
No heavy scents, lipstick, or too much makeup.
Let the dentist know if you have anxiety, allergies, or worries.

Healthy Smiles Start With Simple Habits

Getting ready for the dentist doesn’t have to be hard. Think of it like getting ready for a meeting or job interview—you want to show up feeling your best.

Why These Steps Matter

Here’s why every “don’t” really does matter—not just for your dentist, but for you, too:

Better Diagnosis: Skipping strong foods and sprays helps your dentist spot real issues.
Safer Care: Your real medicine list keeps you safe during treatment.
More Comfortable: Drinking water and managing stress make visits easier.
You Save Time: You get more out of your appointment (and your money).

Use this as your “cheat sheet” for dental visits!

What Happens If You Ignore These Tips?

Everyone makes mistakes, but common “pre-appointment mess-ups” might mean:

Your appointment gets interrupted or delayed
The dentist misses something important, like a cavity or gum problem
You bleed more or things get complicated
Wasted time—you may even have to come back

For example, if you brush too hard before your visit and make your gums bleed, your dentist might miss a real infection. Or you drink a cold soda right before, and your dentist could think you have sensitive teeth when you really don’t. The little things matter.

Real-World Stories

The “Super Flosser”
Emily, nervous before her appointment, flossed super hard and used really strong mouthwash right before her cleaning. During her visit, her gums bled a lot, and her dentist almost missed some gum problems. Later, her dentist explained that over-flossing can cover up bigger issues.
The Coffee Fan
Marcus drank two big espressos before his wisdom teeth check-up. He was really jumpy and his blood pressure was so high that his dentist had to put off his tooth removal.

Nobody’s perfect, but a little know-how can save you a lot of problems.
