Healthy tonsils are pinkish, oval-shaped mounds of tissue sitting on each side of the back of your throat, each roughly the size of a marshmallow. When they’re swollen, they look visibly larger, redder, and may have white or yellow patches on their surface. You can check at home with a mirror and a flashlight in about 30 seconds.
How to Check Your Tonsils at Home
Stand in front of a mirror in a well-lit room, or use a flashlight aimed toward the back of your throat. Open your mouth wide and press the middle of your tongue down with the handle of a clean spoon or a tongue depressor. This keeps your tongue from blocking the view. You should be able to see both tonsils flanking the back of your throat, just behind the arch of tissue on either side.
Look for these specific changes compared to what healthy tonsils look like:
- Size: Swollen tonsils bulge inward and may nearly touch each other at the midline, narrowing the opening of your throat. Healthy tonsils sit relatively flat against the sides.
- Color: Healthy tonsils are a soft pink that matches the surrounding tissue. Inflamed tonsils turn a deeper red.
- Surface texture: White or yellow patches (called exudate) on the tonsil surface are a hallmark of infection. Healthy tonsils have a smooth or slightly bumpy surface without coating.
- Symmetry: If one tonsil is noticeably larger than the other, or the small dangling tissue at the center of your throat (the uvula) is pushed to one side, that’s worth paying attention to.
Keep in mind that tonsil size varies a lot from person to person. Some people naturally have large tonsils that aren’t inflamed. The key is change from your baseline, not absolute size. If your tonsils have always been prominent but aren’t red, coated, or painful, they’re probably just large.
What Swollen Tonsils Feel Like
Visual signs are only part of the picture. Swollen tonsils typically come with a cluster of symptoms you’ll feel before you ever look in a mirror. A sore throat is the most common, often worse when swallowing. You may also notice pain that radiates up to your ears, a scratchy or muffled quality to your voice, and tenderness when you press the lymph nodes just below your jawline on either side of your neck. Swollen lymph nodes there feel like firm, tender lumps about the size of a grape.
Fever, headache, and general fatigue often accompany these symptoms. If you have a sore throat with fever, swollen neck glands, and white patches on your tonsils but no cough, that pattern points more toward a bacterial infection like strep throat. A cough, runny nose, and hoarseness alongside the sore throat suggest a virus is the more likely cause. Even when all four of those bacterial indicators are present, the chance of it actually being strep is still under 60%, which is why doctors use a rapid strep test rather than relying on appearance alone.
Tonsil Stones vs. Actual Swelling
Sometimes what looks like a problem with your tonsils isn’t swelling at all. Tonsil stones are small, white or yellowish, hard bits lodged in the crevices of the tonsil surface. They form from a buildup of food particles, dead cells, and bacteria that calcify over time. They can look similar to the white patches of an infection, but the two feel quite different.
Tonsil stones usually don’t cause fever, significant pain, or red, inflamed tissue. Their signature symptom is bad breath that doesn’t go away with brushing. You might also feel like something is stuck in the back of your throat. The stones themselves are firm and distinct, like a small pebble embedded in the tonsil’s surface, whereas the white patches of tonsillitis are more of a soft coating spread across the tissue. Small tonsil stones often dislodge on their own or with gentle pressure and are generally harmless.
Signs That Need Prompt Attention
Most episodes of swollen tonsils resolve on their own or with treatment within a week. But a few specific warning signs suggest something more serious is happening, like an abscess forming in the tissue around the tonsil.
The clearest red flags are difficulty opening your mouth (your jaw feels locked or extremely stiff), a voice that sounds like you’re talking with a hot object in your mouth, and a uvula that’s visibly pushed to one side. Severe, one-sided throat pain that’s getting worse rather than better over several days also fits this pattern. These symptoms can indicate a pocket of infection has formed next to the tonsil, which needs medical drainage rather than just antibiotics.
Difficulty breathing or swallowing liquids, drooling because swallowing is too painful, and a high fever that won’t come down are also reasons to seek care quickly rather than waiting it out.
When Swollen Tonsils Keep Coming Back
A single episode of tonsillitis is common and usually not a long-term concern. Recurrent episodes are a different situation. The threshold doctors use to consider whether tonsil removal might be worthwhile is fairly specific: seven or more episodes in a single year, five or more per year for two consecutive years, or three or more per year for three consecutive years. Each episode needs to include a sore throat plus at least one of the following: fever above 101°F, swollen neck glands, white patches on the tonsils, or a positive strep test.
If your episodes fall below those numbers, the standard approach is watchful waiting, since most people’s frequency naturally decreases over time. However, factors like severe antibiotic allergies or a history of an abscess forming near the tonsils can tip the balance toward removal even if the episode count is lower. Keeping a simple log of each episode (date, symptoms, whether you had a fever, any test results) gives you and your doctor a clear picture if the pattern continues.
