What Is Gum Disease, and Why Do Your Gums Bleed?
Gum disease is an infection and inflammation of the gums and the tissues that hold your teeth in place. It is caused by plaque and bacteria building up along the gum line. Bleeding gums are often the first sign, and at Mona Lisa Smiles in Barnet we group gum disease into two main stages: gingivitis and periodontitis.

Gingivitis: The Stage You Can Still Turn Around
Gingivitis is the earliest stage of gum disease. It causes red, swollen or bleeding gums but hasn’t yet damaged the bone and tissues that support your teeth. At Mona Lisa Smiles in New Barnet, professional hygiene therapy with one of our dental hygienists, followed by better brushing and flossing at home, can often reverse gingivitis completely.
Periodontitis: When Gum Disease Reaches the Bone
Periodontitis is the advanced stage of gum disease. It develops when gingivitis is left untreated and starts to damage the gums, the bone and the tissues that hold your teeth in place. As bone is lost, teeth can loosen and may eventually fall out. At Mona Lisa Smiles in Barnet, early periodontitis treatment led by Dr Kuljeet Mehta, our Specialist Periodontist, helps manage the condition and protect the teeth you have.
What Causes Gum Disease? It Starts with Plaque
Gum disease is mainly caused by plaque, a sticky film of bacteria that forms on your teeth every day. If brushing, flossing, routine dental check-ups and regular hygiene visits don’t remove it, plaque hardens into tartar. Tartar irritates and inflames the gums, and it can only be removed with a professional clean. The dental team at Mona Lisa Smiles in Barnet often sees gum disease linked to these risk factors:
- Poor or inconsistent oral hygiene
- Smoking or vaping
- Diabetes
- Hormonal changes, including pregnancy
- Certain medications that cause dry mouth
- A family history of gum disease
- Stress


Bleeding Gums and Other Signs Your Gums Need Attention
- Gums that bleed when you brush or floss
- Red, swollen or tender gums
- Bad breath that doesn’t go away
- Gums pulling back from your teeth
- Teeth that feel loose or have shifted
- Teeth that are more sensitive than usua
If you notice any of these signs, book an assessment at Mona Lisa Smiles in New Barnet online or call 020 8449 3411. Bleeding gums treatment is simplest when it starts early.
Why Bleeding Gums Are More Than a Minor Problem
Bleeding gums are easy to ignore, but untreated gum disease can cause receding gums, bone loss, loose teeth, ongoing infection, difficulty chewing and, eventually, tooth loss. Timely gum disease treatment in North London at Mona Lisa Smiles helps protect your teeth, your bite and the appearance of your smile before the damage becomes harder to reverse.
If gum disease has already cost you a tooth, our team can talk you through replacing missing teeth with dental implants and, where needed, rebuilding lost jawbone with bone augmentation.

Frequently Asked Questions
Yes. Bleeding when you brush or floss is often the first sign of gum disease, usually gingivitis. At Mona Lisa Smiles in New Barnet, a hygiene appointment can confirm the cause and start treatment before it progresses.
Yes, at the early stage. Gingivitis can often be reversed with a professional clean and better daily brushing and flossing. Periodontitis can’t be fully reversed once bone has been lost, but at Mona Lisa Smiles it can be managed and kept stable with treatment and regular periodontal maintenance.
Yes. Untreated periodontitis damages the bone and tissues that hold teeth in place, so teeth can loosen and eventually fall out. Treating gum disease early at Mona Lisa Smiles in Barnet helps protect the teeth you have.
Most patients benefit from a hygiene visit about every six months, often alongside their routine check-up. If you have periodontitis, the team at Mona Lisa Smiles may recommend more frequent visits as part of a periodontal maintenance plan.
Not always. Most cases of gingivitis and early gum disease are treated by the dental hygienists at Mona Lisa Smiles in Barnet. For advanced or complex periodontitis, patients can see Dr Kuljeet Mehta, our GDC-registered Specialist Periodontist, at the same practice.
