How To Deal With Mouth Ulcers

 

What Are Mouth Ulcers?

 

Mouth ulcers are small, painful sores that develop inside the mouth, on the gums, tongue, or inner cheeks. They are usually round or oval with a white or yellow center and a red border. Most are harmless and heal on their own within 1-2 weeks.

 

Causes of Mouth Ulcers

 

  • Minor injury (biting your cheek, dental work, or irritation from braces)
  •  
  • Stress or hormonal changes
  •  
  • Food sensitivities (citrus, spicy foods, or acidic foods)
  •  
  • Nutritional deficiencies (iron, vitamin B12, folate)
  •  
  • Underlying health conditions (celiac disease, Crohn’s disease, allergies)

 

How to Treat Mouth Ulcers

 

  • Maintain oral hygiene: Brush gently with a soft-bristled toothbrush and avoid toothpaste with sodium lauryl sulfate.
  •  
  • Avoid triggers: Stay away from spicy, acidic, or rough foods that can irritate the ulcer.
  •  
  • Pain relief: Use over-the-counter topical gels or mouth rinses containing benzocaine or hydrogen peroxide to numb pain and promote healing.
  •  
  • Rinse with salt water: Dissolve 1 teaspoon of salt in a cup of warm water and rinse your mouth several times a day.
  •  
  • Stay hydrated: Drink plenty of water to keep your mouth moist and support healing.
  •  
  • Address deficiencies: If you suspect a vitamin or mineral deficiency, consider supplements after consulting a healthcare provider.

 

When to See a Doctor

 

  • Ulcers last longer than 2 weeks
  •  
  • Frequent or unusually large ulcers
  •  
  • Difficulty eating or drinking
  •  
  • High fever or other concerning symptoms

How long do mouth ulcers usually take to heal?

 

How Long Do Mouth Ulcers Take to Heal?

 

Mouth ulcers usually heal on their own within 7 to 14 days. Most do not require medical treatment.

  • Small ulcers often heal faster, sometimes in less than a week.
  •  
  • Larger or more painful ulcers may take up to two weeks to fully disappear.

Tips for faster healing:

  • Keep your mouth clean by rinsing with salt water.
  •  
  • Avoid spicy, acidic, or rough foods that can irritate the ulcer.
  •  
  • Use over-the-counter gels or ointments to reduce pain and speed up healing.

FAQ

How fast does the Quickie Nasal Spray work?

Most patients feel relief within 15 minutes. We have both short-term relief ingredients as well as longer-term relief to keep you feeling better, longer. Some say it’s like turning off their allergies.

What symptoms does the Nasal Spray treat?

Sneezing runny nose, nasal congestion, post-nasal drip, sinus pressure, itchy nose. Great for outdoor allergies, indoor dust, or when pollen spikes unexpectedly.

Will it cause rebound congestion like Afrin?

No, this formula uses a microdose of oxymetazoline, balanced with anti-inflammatory and moisturizing ingredients to reduce the risk of rebound congestion. Clinical studies over the last decade show that when oxymetazoline is combined with a corticosteroid, it can be used safely over the long term without causing rebound symptoms.

What’s the difference between this and over-the-counter sprays?

Quickie Spray combines up to five prescription-strength ingredients into a single, personalized formula — targeting multiple symptoms like congestion, post-nasal drip, and inflammation. OTC sprays typically address just one symptom and lack the synergy of a customized blend.

Does it have a bad taste or drip down the throat?

Some ingredients like azelastine may cause a slight taste, but many patients find it milder than traditional OTC sprays. Proper spray technique (head forward, not tilted back) helps minimize drip.We also offer an alternative formulation with olopatadine, which has a gentler taste profile and may be preferred by taste-sensitive patients.

Can I use it with my other allergy meds?

Quickie is designed to replace most other allergy medications. But it is designed to compliment allergy immunotherapy for long-term relief. If you’re currently taking other antihistamines or nasal sprays, tell your Curex provider, so we can adjust your formula to avoid overlap or interactions.

Is this FDA-approved?

No, Quickie is a personalized compounded prescription prepared by licensed U.S. pharmacies based on your doctor’s evaluation. Compounded medications are not FDA-approved as commercial products, but they are regulated under federal and state pharmacy laws.

Are there any side effects?

Possible side effects include nasal dryness, mild irritation, or occasional nosebleeds. These are typically mild and manageable. Let your Curex provider know about any bothersome or serious effects, so we can fine-tune your prescription if needed.

How long should I use it for?

Quickie is safe for daily use, especially during the first 3–6 months of allergy immunotherapy, when symptoms are still active. Your Curex provider may adjust your dose or frequency as your immune system builds tolerance.

Will it make me drowsy?

Quickie is designed to be non-sedating, so you can use it before work, school, or exercise without feeling groggy or foggy. In rare cases where drowsiness is reported, let your Curex provider know—we can easily adjust the formula to better suit your needs.

Can my child use Quickie Nasal Spray?

Yes, Quickie Spray can be prescribed for children aged 6 and up, based on your provider’s clinical evaluation.

How often should I use it?

Follow the instructions from your Curex provider.Most patients are advised to use one spray per nostril, twice daily — morning and evening — for consistent relief.
