At Sonria Dental Clinic, we provide periodontal care and gum disease treatment in Central London. A healthy mouth naturally contains hundreds of different types of bacteria, most of which are harmless and live in balance. However, when teeth are not cleaned thoroughly, bacterial deposits can build up along the gum line, forming dental plaque can create conditions that allow harmful bacteria to multiply, increasing the risk of gum inflammation and periodontal disease.
Periodontitis is a common and serious form of gum disease that affects the gums and the structures supporting your teeth. It develops where bacteria accumulate on the teeth and along the gum line, triggering an inflammatory response. Common signs of gum inflammation include redness, swelling and bleeding when brushing your teeth. If left untreated, periodontitis can damage the tissues and bone that support your teeth.
Inflammation is part of the body’s natural defence against harmful bacteria. However, when gum inflammation persists, it can gradually damage the tissues that support your teeth. If periodontitis is left untreated, the inflammation can extend below the gum line and along the tooth roots, damaging the periodontal ligament and supporting bone. Over time, this damage can cause teeth to become loose and may eventually lead to tooth loss.
Periodontal bacteria are naturally present in the mouth, but they can become harmful when conditions allow them to multiply. When plaque, a sticky layer of bacteria and food debris, is not regularly removed from the teeth, bacteria can accumulate, particularly in hard-to-reach areas such as between the teeth. As harmful bacteria multiply, they produce substances that irritate the gums and trigger inflammation. This early stage of gum inflammation is known as gingivitis.

Associate Clinical Lecturer
I am a highly trained oral surgeon with a strong commitment to providing high-quality, pain-free treatment to all my patients. Having worked with a diverse range of individuals, I have developed excellent communication skills and excel at putting patients at ease and clearly explaining procedures, expected outcomes and post-treatment follow-up needs. I have extensive experience performing oral surgery and oral medicine, including difficult extractions, dental implants, restorations and bone augmentation procedures. In addition, I am adept at diagnosing and managing treatment of infective, premalignant and immunological oral diseases.
Throughout my career, I have trained and mentored numerous dental students, new dentists and other clinical and non-clinical staff. This includes lecturing and teaching university and continuing education courses in oral medicine as well as assessing progress and providing individualised support to assist students and colleagues in learning new techniques and procedures.

“The patient’s needs are truly a priority. We deliver personalised services of the highest quality.”
I studied Prosthodontics, Periodontics and implant dentistry. I have worked for more than fifteen years in Periodontics and implantology focusing on saving natural teeth and replacement using the latest technology and treatments.
My passion is knowledge. Keeping up to update with the latest technologies and treatment techniques leads me to study both in England and outside for the necessary learning to provide the best for my patients.
On the other hand, meditation, yoga and different sports allow me to maintain a healthy lifestyle through mind-body harmony.
Serving and giving my best to the patients embodied in the understanding of biology is what I absolutely love about dentistry. The patients for whom I have the most empathy is those who arrive when they have no hope of keeping their natural teeth and complex cases regarding bone regeneration and dental implants.
Sonria is a clinic where the patient’s needs are truly a priority. The team are focused on delivering personalised services of the highest quality to patients.
I speak Spanish and English.
Please note – bleeding from the gums may be less noticeable in smokers!


As Sonria Dental Clinic in Central London, we understand that when bacterial plaque is not removed from the gums and surfaces of your teeth while it is still soft, minerals can gradually build up and cause it to harden in to a substance known as tartar.
When tartar remains on the teeth for long periods, it can encourage bacterial plaque to build up towards the tooth roots. This can trigger inflammation deeper within the gums, weakening the attachment between the gums and tooth roots and creating gaps known as periodontal pockets. These pockets provide an environment where harmful bacteria can grow and multiply, allowing gum disease to progress. As the bacteria continue to spread, they release toxins that trigger further responses from the body’s defence system.
If periodontal inflammation is left untreated, it can damage the structures that support your teeth, including the surrounding bone. As these supporting structures weaken, teeth may gradually become loose and could eventually fall out. In some cases, affected teeth may need to be extracted if they cannot be saved. These problems may also occur alongside the symptoms of gum disease described above.
Periodontal infections typically involve several types of bacteria, particularly anaerobic bacteria such as Treponema denticola and Porphyromonas gingivalis. Another bacterium, Aggregatibacter actinomycetemcomitans (formerly known as Actinobacillus actinomycetemcomitans), is associated with certain forms of periodontitis, including forms that can affect younger patients.

Successful periodontal disease treatment focuses on removing the bacterial plaque that contributes to gum disease and maintaining good oral hygiene practices. For patients with periodontitis, several treatment options are available, depending on the severity of the condition:
Professional dental cleaning involves removing soft deposits from accessible areas of the teeth, followed by polishing and fluoride treatment. Depending on the severity of the gum disease, additional cleaning appointments and oral hygiene guidance may be required. Your dentist will also remove bacterial deposits and tartar from the tooth root surfaces and gum pockets to help manage periodontal disease.
In some cases, antibiotics may be prescribed to help treat active or persistent gum infections that have not responded adequately to oral hygiene measures. Depending on the patient’s condition, the dentist may recommend microbiological testing to help determine the most appropriate treatment.
After several weeks, your dentist or periodontist will carry out a thorough assessment of your gums to evaluate the progress of your treatment. A specialised instrument called a periodontal probe is used to measure the depth of any periodontal pockets and check for gum bleeding. If periodontal pockets are still present, your dentist may recommend further treatment options, including corrective periodontal surgery.
In some cases, periodontal surgery may be carried out to remove plaque bacteria and deposits from beneath the gums, including periodontal pockets and the root surfaces at the furcations (where the tooth roots divide). Under local anaesthesia, the gum tissue is gently lifted to allow the dentist to clean the root surfaces under direct vision and remove bacterial deposits. In certain cases, bone loss may also be treated using specialised regenerative techniques. Once the procedure is complete, the gums are sutured back into position around the teeth.
Following the initial phase of gum disease treatment, your dentist will assess the condition of your gums at regular intervals to monitor inflammation and treatment progress. The frequency of your follow-up appointments will depend on the severity of your gum disease and your individual risk of further progression. Follow-up visits are usually scheduled every three to six months.
