Published with the patient’s consent. In the photo, the top half shows the teeth before treatment and the bottom half after. Every mouth is different: your own plan follows an examination.
Before: the situation
The upper front teeth are several different colours: the central incisors are cream-yellow with fine surface lines, one lateral incisor is bluish-grey and more opaque than the rest, and both canines show a yellow-orange band near the gum. An orange-brown line follows the gum margin of the central incisors, and the biting edges are uneven, with one lateral incisor shorter than its partner.
What was wrong, and why it matters
Front teeth that differ in colour make a smile look patched together, even when each tooth is sound. A single tooth that is bluish-grey and more opaque than its neighbours can reflect a change inside the tooth, such as an old injury to the nerve, or an older restoration. Yellow-orange bands near the gum often mean the thinner enamel at the neck lets the darker inner layer show through, or that a margin there has stained.
A discoloured line along the gum margin is worth checking, because staining at that edge collects plaque and can hide a leaking margin or early decay. Uneven edges, with one lateral incisor shorter than its partner, also change the proportions of the smile and how the front teeth share load in the bite. Treating colour without addressing these causes lets the problem return.
The solution
The after photo shows the upper front teeth in one bright, even shade, with symmetrical edges and no discoloured band at the gum margins. The greyish tooth now matches its neighbours, and the new ceramic restorations follow a balanced outline from side to side.
In a case with several different problems, Dr. Marina’s approach is to assess each tooth first: why it is discoloured, whether it needs treatment inside, and how much natural structure can be kept. That diagnosis becomes one structured plan, so the patient can see which tooth needs what and in which order. The final shape and shade are agreed in a mock-up and checked against the bite.
How a case like this is planned and carried out
Examination, X-rays, photographs and a digital scan of each front tooth
Check of the greyish tooth and the stained gum margins before any cosmetic step
One written plan setting out what each tooth needs and in what order
Digital smile design and a mock-up of the final shade and edge line
Restorations made with the ceramist in the dental lab in the same building
Bite and shade reviewed after fitting
After: the result
The front teeth now read as one set: a single bright shade, matching translucency and symmetrical edges. The greyish tooth and the yellow-orange necks are no longer visible, and the gum margins look clean.

In Dr. Marina Antoniuk’s words
Dr. Marina AntoniukMy key strength lies in comprehensive clinical thinking and the ability to develop structured, clear, and understandable treatment plans for patients, including the most complex multidisciplinary cases.
With several teeth discoloured for different reasons, the value of the plan was in making each step clear: what each tooth needed, and why, before the smile was rebuilt as one.

Questions about this kind of case
What does an orange-brown line along the gum edge of the front teeth mean?
It is staining where the tooth meets the gum. Common causes are plaque and surface stain, the stained edge of an older filling or crown, or early decay at the margin. A clinical check and X-ray show which applies: cleaning may be enough, while a leaking margin needs the restoration redone. Dr. Marina Antoniuk at Creative Arts in Dubai checks these margins before planning any cosmetic work.
Why do the necks of front teeth turn yellow-orange near the gum?
Enamel is thinnest near the gum, so the naturally yellower inner layer shows through more there, and the effect grows with age or if the gum recedes. Staining along older restoration margins can add an orange tone. The cause decides the plan, from cleaning to new restorations. Dr. Marina Antoniuk at Creative Arts in Dubai, who speaks English and Russian, explains which applies after examination.
