Dry Mouth (Xerostomia) Treatment in London

Dry mouth, medically known as xerostomia, happens when the salivary glands do not produce enough saliva to keep the mouth comfortable and healthy. Saliva is more than just moisture – it helps protect teeth from decay, supports digestion, keeps breath fresh, and makes chewing and swallowing easier.

When saliva production decreases, patients may notice discomfort, difficulties with eating or speaking, and an increased risk of dental problems. At Thousand Smiles, our dental team can diagnose the cause of dry mouth and provide tailored treatments to restore comfort and protect oral health.

Why Saliva Matters

Saliva plays a crucial role in oral and overall health by:

Washing away food particles and debris
Neutralising acids that damage teeth
Helping with chewing, swallowing, and speaking
Supporting taste and digestion
Protecting teeth and gums against decay and infection

Without sufficient saliva, even simple daily tasks such as eating or wearing dentures can become challenging.

Signs and Symptoms of Dry Mouth

Constant dryness or stickiness in the mouth
A dry or rough-feeling tongue
Bad breath
Hoarseness or a sore throat
Thick or stringy saliva
Difficulty speaking, chewing, or swallowing
Changes in taste

Common Causes of Dry Mouth

Dry mouth can develop for a variety of reasons, including:

Medications – Many prescribed and over-the-counter medicines, such as those for blood pressure, allergies, depression, and anxiety, may reduce saliva flow.
Age-related changes – As people age, saliva production can naturally decrease, often made worse by other health conditions or long-term medication use.
Cancer treatment – Radiation therapy to the head or neck may damage salivary glands.
Medical conditions – Diabetes, stroke, Alzheimer’s disease, Sjögren’s syndrome, and autoimmune disorders can all contribute.
Lifestyle habits – Smoking, alcohol consumption, and recreational drug use are frequent triggers.
Nerve damage – Injury or surgery affecting the head and neck can reduce saliva production.
Mouth breathing and snoring – These can worsen dryness, particularly at night.

Possible Complications

If left untreated, dry mouth can increase the risk of:

Gum disease and tooth decay
Oral infections such as thrush
Cracked lips and sores in the mouth
Difficulty eating and poor nutrition

Diagnosing Dry Mouth

Our dentists will begin by reviewing your medical history and discussing your symptoms. This may include:

Checking medication lists for potential side effects
Examining the mouth and salivary glands
Ordering diagnostic tests or scans if required
Biopsy or specialist referral if autoimmune conditions are suspected

Accurate diagnosis ensures that treatment is tailored to the individual’s needs.

Treatment Options

Management of dry mouth depends on its underlying cause. Treatment may include:

Medication adjustment – If a prescribed drug is responsible, your dentist may liaise with your GP to find alternatives or adjust the dosage.
Moisturisers and saliva substitutes – Special gels, sprays, and rinses help lubricate the mouth.
Prescription medication – Drugs such as pilocarpine can stimulate saliva production in some patients.
Protective dental care – Fluoride rinses, high-strength toothpaste, or custom trays may be recommended to prevent cavities.
Every plan is designed to relieve discomfort, protect teeth, and restore quality of life.

Self-Care and Aftercare Tips

Alongside professional treatment, simple lifestyle adjustments can make a big difference:

Sip water regularly, especially during meals
Chew sugar-free gum or suck sugar-free lozenges to stimulate saliva
Avoid alcohol, caffeine, and tobacco products
Use a humidifier at night
Keep lips moisturised with a balm
Choose sugar-free and low-acid foods and drinks

Maintain daily brushing and flossing with fluoride products

Regular dental check-ups are essential to monitor oral health and prevent complications.

Cost of Dry Mouth Treatment in London

The cost of managing dry mouth varies depending on the underlying cause, the need for diagnostic tests, and the type of treatment prescribed. At Thousand Smiles, we provide a clear breakdown of fees during your consultation and discuss all available options so you can make an informed choice.

Who Is Suitable for Treatment?

Most patients experiencing persistent mouth dryness are suitable for assessment and treatment. It is especially important to seek help if you:

Have ongoing discomfort that affects daily life
Experience frequent infections or bad breath
Take long-term medications with known side effects
Have a medical condition linked to reduced saliva flow

Alternatives and Supportive Options

In some cases, direct treatment may not be possible (for example, if cancer therapy permanently affects salivary glands). In these situations, supportive care such as saliva substitutes, fluoride treatments, and dietary guidance can help manage symptoms and protect oral health.

Frequently Asked Questions

Is dry mouth permanent?

It depends on the cause. If medication is responsible, symptoms may improve with adjustments. Conditions such as gland damage may cause long-term issues but can still be managed.
Will drinking more water cure dry mouth?

Staying hydrated helps, but water alone often isn’t enough if the salivary glands are underactive. Other treatments are usually needed.
Can dry mouth cause tooth decay?

Yes. Lack of saliva increases the risk of cavities and gum problems, which is why dental care and fluoride protection are so important.
Can over-the-counter products help?

Yes. Saliva substitutes and moisturising gels can provide relief, but professional advice ensures you choose the most effective option.
When should I see a dentist?

If you’ve had persistent symptoms for more than a few weeks, or if dryness is affecting eating, speaking, or oral health, it’s time to book an appointment.
