Your tonsils are visible without any special equipment. All you need is a mirror, a good light source, and the right technique to open your throat wide enough. They sit on each side of the back of your throat, just behind and above the base of your tongue, and most people can spot them in under a minute once they know where to look.
What You Need
A bathroom mirror works fine, but a handheld mirror gives you more control over the angle. You also need a bright light source. The key is positioning the light as close to your line of sight as possible, so the beam shines straight into your open mouth rather than casting shadows. A smartphone flashlight held just below your chin or next to your cheek works well. Overhead bathroom lighting alone often leaves the back of the throat too dark.
If you want an even closer look, a small dental mirror (the kind with a round head on a handle) lets you angle past the tongue and see deeper. Warm it under warm water first to keep it from fogging up when it enters your mouth.
Step by Step: Finding Your Tonsils
Stand in front of your mirror with the light source ready. Open your mouth as wide as you comfortably can, then say “ahhh” in a long, sustained tone. This lifts your soft palate (the fleshy area at the roof of your mouth toward the back) and drops the base of your tongue, opening up the view to your throat.
Look past your tongue toward the back of your throat. On either side, you’ll see two vertical folds of tissue, almost like curtains. These are the tonsillar pillars. Your tonsils sit in the pocket between those folds. In some people they bulge out prominently; in others they’re tucked further back and harder to spot.
If your tongue keeps getting in the way, gently press it down with the handle of a clean spoon. Place it on the front two-thirds of your tongue and push straight down. Avoid pressing too far back, which triggers the gag reflex. Breathe slowly through your mouth while you look.
What Healthy Tonsils Look Like
Healthy tonsils are pinkish, oval-shaped mounds of tissue. They match the color of the surrounding throat tissue fairly closely. Their surface is slightly bumpy or irregular, with small pits called crypts scattered across them. These crypts are completely normal and are part of how tonsils trap bacteria and debris as part of your immune system.
Tonsil size varies enormously from person to person. Doctors grade them on a 0 to 4 scale based on how much of the throat opening they occupy. Grade 1 tonsils take up less than 25% of the space between the two sides of the throat, so they may look like small bumps barely peeking out from behind the pillars. Grade 3 or 4 tonsils fill 50% to over 75% of that space and can nearly touch each other in the middle. Children and teenagers tend to have larger tonsils than adults, and size alone doesn’t mean anything is wrong.
Signs of Tonsil Stones
One of the most common reasons people look at their tonsils is that they’ve noticed something white or yellow at the back of their throat. Tonsil stones are small, pale yellow or off-white masses that form inside the crypts when dead cells, mucus, and bacteria calcify. They can look spongy or hard, and they range from barely visible specks to pea-sized lumps. Many people first discover them after coughing one up or noticing persistent bad breath.
Tonsil stones are not an infection. They’re a nuisance, not a danger. You can sometimes see them lodged in the crypt openings when you shine a light on your tonsils. They occasionally dislodge on their own with gargling.
Signs of Infection
Infected tonsils look distinctly different from healthy ones. The tissue turns noticeably red and swollen, and you may see white or yellow patches of pus spread across the surface. These patches differ from tonsil stones because they look more like a coating or streaks rather than a discrete, solid lump sitting in a pit.
Other visual signs of a bacterial throat infection include tiny red spots on the roof of the mouth (called petechiae) and visibly swollen tonsils that have grown significantly larger. If you also have a fever, painful swallowing, and swollen glands along the front of your neck but no cough or runny nose, the pattern points toward a bacterial cause like strep rather than a common virus.
One thing worth paying attention to is symmetry. Both tonsils being equally swollen during an illness is typical. One tonsil that’s noticeably larger than the other, especially if it stays that way after other symptoms resolve, warrants a closer look from a doctor.
Taking a Photo for Your Doctor
If you’re trying to document what your tonsils look like for a telehealth visit or to show your doctor later, a smartphone camera can produce a useful image with the right approach. The biggest factor is light. More light means a sharper, clearer photo with more accurate color. Turn on your phone’s flash, and if possible, add a second light source like a desk lamp aimed at your open mouth.
Have someone else take the photo if you can. They should hold the phone perpendicular to your open mouth, centering the tonsils in the frame, from about six to eight inches away. If you’re doing it alone, use the front-facing camera and a mirror to guide your aim. Keep the phone steady and tap the screen to focus on the back of your throat before snapping the photo. Take several shots at slightly different angles so you have options. Daylight from a window produces the most accurate color, which matters when your doctor is trying to assess redness or the color of any patches.
